TEC1-12715 Peltier Module The TEC1-12715 40x40mm Thermoelectric Cooler 15A Peltier Module is the simple application of the Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 40mmx40mm. Thermoelectric coolers are also known as TEC or Peltier modules create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity. The TEC1-12715 40x40mm Thermoelectric Cooler 15A Peltier Module is the simple application of the Peltier Thermoelectric Effect. The module features 127 semiconductor couples in the area of 40mmx40mm. The TEC1-12715 Thermoelectric Peltier Cooler Module works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or another block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it. A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying the DC power source to a TEC, heat will be transferred from one side of the module to the other. It creates a cold and hot side. They are widely used in industrial areas, for example, computer CPUs, CCDs, portable refrigerators, medical instruments, and so on. read our blog explaining Peltier module working , It explains the working principle of a Peltier Module, which involves transferring energy between two metals through electrical current. TEC1-12715 Peltier Module Operating Tips: Do not exceed Imax or Vmax when operating a module. Please carry out moisture protection options (sealing) in final application use. Life expectancy: 200,000 hours. Failure rate based on longtime testings: 0.2%.

W1209 Digital Temperature Controller Thermostat Module The 12V W1209 Digital Temperature Controller Module With Display and NTC Temp Sensor is a low-cost and top-quality solution if you want temperature control features in your projects. This powerful 12V module is perfect for both heating and cooling jobs, giving you a massive temperature range from -50°C to 110°C with solid 0.1°C accuracy. The w1209 temperature controller comes with a high-quality waterproof NTC temperature sensor, so you get correct readings every single time. Setting it up is easy. With its built-in display and simple buttons, you can easily set trigger temperatures without any coding knowledge. The onboard relay can automatically switch power for both your home AC appliances and 12V DC devices. The W1209 thermostat is perfect for creating your own automatic fans, coolers, heaters, and pumps. A must-have for student projects, DIY incubators, aquariums, and other smart automation ideas. Also, read our blog W1209 Temperature Controller Setting detailing the variety of W1209 Setting Modes. W1209 Module Diagram: Displaying the current temperature: The Thermostat will display the current temperature in °C by default. When in any other mode making no input for approximately 5 seconds will cause the thermostat to return to this default display. Setting the trigger temperature: To set the trick to a temperature press the button marked 'SET'. The seven-segment display will flash. You can now set a trigger temperature ( in °C) using the '+' and '-' buttons in 0.1° increments. If no buttons are pressed for approximately 2 seconds the trigger temperature will be stored and the display will return to the current temperature. Setting the Parameters for the W1209 Digital Temperature Controller Thermostat Module : To set any parameter, first long-press the 'SET' button for at least 5 seconds. The seven-segment display should now display 'P0'. This represents parameter P0. Pressing the '+' or '-' buttons will cycle through the various parameters ( P0 to P6). Pressing the 'SET' button whilst any of these parameters are displayed will allow you to change the value for that parameter using the '+' and '-' buttons. When finished setting a parameter, press the set button to exit that option. If no buttons are pressed for approximately 5 seconds that thermostat will exit the perimeter options and will return to the default temperature display. Heating Parameter P0: P0 has two settings, C and H. As the relay energizes when the temperature is reached, the default setting C can be utilized to connect to an air conditioner. When the required temperature is found, setting H results in de energizing the relay. Any heating apparatus can be controlled by it. Hysteresis Parameter P1: The temperature range that must alter before a relay will change status is determined by this parameter. Parameter P2 (Upper Limit Temperature): P2 limits the maximum trigger temperature that can be set. It serves as a safety feature that prevents the user from setting a trigger temperature that is too high. Parameter P3 (Lower Limit Temperature) : P3 limits the minimum trigger temperature that can be set. As a safety measure, it prevents the user from setting a low triggering temperature. Offset Correction Parameter P4: If there is a discrepancy between the displayed temperature and the actual temperature measurement using this parameter, changes can be made. Delay Parameter P5: The delay parameter P5 can be used to control how long the relay switches after the trigger temperature has been attained. It can be set for up to ten minutes at a time, in one-minute intervals. Alarm Parameter P6: When the temperature exceeds the specified level, this parameter causes the relay to shut off. As a warning, the display will flash "---" when an alarm condition exists. When the temperature reaches this point, the relay will not re-energize.

XH-W1219 12V Digital Temperature Controller The XH-W1219 12V digital temperature controller is a device that allows you to control the temperature of a system or process using a digital interface. It typically includes a temperature sensor, a control algorithm, and an output mechanism to control the temperature. The XH-W1219 is a 12V version, meaning that it operates at a voltage of 12V DC. It may have inputs for setting the temperature setpoint and control parameters, as well as outputs for controlling devices such as heating elements or cooling fans. The controller may also have a display for showing the current temperature, setpoint, and other information. It may be used in a wide range of applications including HVAC systems, incubators, ovens, and other temperature-controlled environments. The XH-W1219 module is basically the same as the popular W-1209 module except it has a 2nd display added to always show the current trigger point along with the current temperature.   When programming the parameters in the module, the dual displays make it a little easier see what you are doing since the top display shows the parameter selected while the bottom display shows the value you are setting.  This module is slightly larger than the W-1209 and so will not fit in the acrylic case designed for that module. A built in STM8S uC allows you to configure the module using the display and 3 pushbuttons.  All settings are saved into non-volatile memory and are preserved during a power cycle. The temperature is sensed by a high accuracy waterproof NTC 10K Thermistor that has a range of -30°C to 110°C (-22°F to 230°F) .  The sensor cable is about 13? long, but it is possible to splice wire to lengthen the cable if needed. The relay is rated for up to 120VAC @ 10A and 14VDC @ 10A.  When the relay is energized an LED is lit.    It is also possible to use the relay on this module to switch higher power relays if you want to control a lot of power. Note : This board is Nuvoton based. Button Parameters: P0 = (Heat / Cool) sets whether the relay is energized or de-energized when trigger temperature is reached. P1 = (Hysteresis) sets the difference in degrees between the Trigger temp and when the relay changes state P2 = (Max Temp) sets the maximum Trigger temp that can be set P3 = (Min Temp) sets the minimum Trigger temp that can be set P4 = (Temp Correction) sets an offset to use for the displayed value P5 = (Delay) sets a time delay between when the Trigger temp is reached and when the relay is switched P6 = (Alarm) sets a high temperature ‘alarm’ trip point
