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 Temperature measurement in medical equipment Temperature measurement in industrial processes Temperature measurement in automotive systems Temperature measurement in environmental monitoring Temperature measurement in consumer electronics.

10K Thermistor Temperature Sensor Module(3 Pin) Thermistor Temperature Sensor Module is very sensitive to ambient temperature. It is 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.

10Kg Load Cell A 10 kg load cell is a load cell that is designed to measure forces or weights up to 10 kg (22 lbs). Each load cell can measure the electrical resistance, which changes in response to and is proportional to the strain (e.g., pressure or force) applied to the bar. You can use this gauge to determine how heavy an object is, if the weight of an object changes over time, or if you simply need to detect the presence of an object by measuring strain or load applied to a surface. This straight bar load cell is made of Aluminium alloy and can read a weight capacity of 10KG. It has four lead wires for connecting to the HX711 A/D Pressure Sensor. It is simple to use with a driving voltage of 5-10V and produces output voltage as force changes over it. Installation of the Sensor is also a simple task; it is necessary to fix one end through the screw hole and leave the other end floating in order to indicate the direction of the gravitational force exerted. Special care must be taken not to directly push the white plastic cover part of the sensor in order to avoid damage. A load cell is used in an electronic weighing machine to measure the load or pressure produced by the load; most load cells use the strain gauge method, which converts the pressure (force) into an electrical signal; these load cells have four strain gauges connected in a Wheatstone bridge formation. When we apply a load, the strain gauge resistance changes, and thus the output voltage from the load cell changes, allowing us to measure the load value. If you want to use this load cell you need few essential elements like hx711, Arduino , jumper wires , display module and soldering tools . There are other types of load cell also available , according to your requirement Applications: Electronic platform scale Digital scale Parcel post scale Electronic balance Also check 3 Kg Load Cell with the model name YZC-133.

2 Inch Water Flow Sensor YF - DN50 The YF-DN50 water flow sensor is a device that is used to measure the flow rate of water. It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device. The sensor is commonly used in applications such as irrigation systems, water treatment plants, and industrial process control. It is often preferred over other types of flow sensors because it is easy to install and has a low cost. The YF-DN50 sensor is designed to be installed in a pipe with a diameter of 50mm or 1.97 inches. The YF-DN50 water flow sensor is a large 2 inch diameter Water Flow meter Sensor that can be used to measure flow rate from 10 - 200 Liter/min This water flow sensor consists of a plastic valve body, a rotor assembly and a Half effect current sensor. As the water flows through this sensor the rotor rotates and the speed of it changes with changes in the rate of flow of water. The hall-effect sensor outputs the corresponding pulse signal. The output of the flow sensor is proportional to the water flow. The more the water flowing more are the pulses.

Flex Sensor 2.2″ Bend Sensor for Hand Gesture Recognition The 2.2-inch Flex Sensors are commonly used in Robotic Gloves and other Robotic Control applications. It can be used to analyze how much material is being bent. This flex sensor is 2.2” long and has two output leads that act like a variable resistor. That is the resistance between two pins change based on how much the sensor is bent.  It is commonly used along with another resistor to build a voltage divider circuit and then obtain a variable voltage based on the change in resistance of the sensor. The flex sensor is a bend-detecting sensor that has got numerous applications in robotics, medical and haptic technology. The resistance of these sensors changes in accordance with the bend, which can be measured using any microcontroller. This is a simple 2.2" long flex sensor that can be used/interfaced with an Arduino. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of the bend). The connector is 0.1" spaced and breadboard friendly.  Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.
