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

10K Thermistor Temperature Sensor Module(3 Pin) Thermistor Temperature Sensor Module is very sensitive to ambient temperature. This electronic part generally used to detect the temperature of the surrounding environment. Through potentiometer adjustment, it is possible to change the temperature detection threshold. DO output can be directly connected to the microcontroller to detect high and low, by detecting temperature changes in the environment. The temperature detection range of the module is between 20 and 80 degrees Celsius. This sensor module can be replaced with a line temperature sensor for controlling the water temperature, water tank, etc. Generally, the 4-wire method of thermistor measurement is the most accurate because there is effectively no current flowing in either of the measurement cable wires and therefore no added resistance due to the cable wires.

DHT11 Humidity and Temperature Sensor The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate, and works in a smaller range of temperature/humidity. But despite its disadvantages over DHT22, it is a smaller and less expensive sensor for temperature and humidity measurement.

As a result, the SenseCAP ONE tiny weather sensor is compatible with any data logger that supports RS485 (MODBUS-RTU) or SDI-12. Hardware Overview

10K Temperature Sensor (Thermistor) A 10K temperature sensor (also known as a thermistor) is a type of resistor that changes its resistance value in response to changes in temperature. The "10K" refers to its resistance value at a temperature of 25°C, which is 10,000 ohms. Thermistors are commonly used in temperature sensing and control applications because of their high sensitivity and fast response time. They are often preferred over other temperature sensors such as thermocouples and RTDs because they are smaller, cheaper, and easier to use. There are two main types of thermistors: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a resistance that decreases as the temperature increases, while PTC thermistors have a resistance that increases as the temperature increases. Thermistors are inexpensive, easily obtainable temperature sensors.  They are easy to use and adaptable.  Circuits with thermistors can have reasonable output voltages - not the millivolt outputs thermocouples have.  Because of these qualities, thermistors are widely used for simple temperature measurements.  They're not used for high temperatures, but in the temperature ranges where they work, they are widely used. Applications: Temperature control in HVAC systems Medical equipment Industrial processes Automotive systems Environmental monitoring Consumer electronics.
