AM2120 Temperature and humidity sensor with JST connector

The AM2120 Digital Temperature and Humidity Module is a sensor that measures both temperature and humidity and provides calibrated digital signal outputs. It utilizes advanced digital module acquisition technology and temperature and humidity sensor technology to ensure high reliability and excellent long-term stability of the product. This product is characterized by outstanding quality, extremely fast response times, high noise immunity and high cost efficiency. Each sensor undergoes a precise calibration in a specialized humidity calibration laboratory. The calibration coefficients are stored in the form of programs in the sensor's microcontroller and are used during signal processing in the sensor.

The sensor has a standard one-wire interface, which simplifies and speeds up system integration. Its tiny size and very low power consumption make it suitable for various applications, even in demanding environments. It can transmit signals over distances of more than 20 meters, making it the ideal choice for a variety of applications, even the most demanding ones.

Pre-built libraries are available for use with Arduino, ESP, ESP, Raspberry etc. The sensor is compatible with the DHT library.
