Temperature, humidity and pressure sensors
Choose sensors that transmit information about temperature, humidity and pressure. Suitable for building your own weather station, measuring pool water temperature or for automatic watering systems. The sensors work on many principles - temperature sensors, for example, measure contactlessly infrared emissions or the thermoelectric effect in thermocouples. Humidity sensor measures the resistance between two points, and the pressure sensor uses changes in the shape of the aneroid cell.
