The AM2302 Humidity Capacitance Digital Temperature and Humidity Module is a temperature and humidity composite sensor with a calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. The sensor consists of a capacitive sensing element and a high precision temperature measuring element connected to a high performance 8-bit microcontroller. Therefore, the product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability and high cost performance. Each sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the microcontroller as a program, and these calibration coefficients are called internally during the processing of the detection signal. The standard single bus interface makes system integration quick and easy. Ultra-small size, extremely low power consumption, and signal transmission distance of more than 20 meters make it the best choice for any application and even the most demanding applications. The product is easy to connect with 3 leads (single bus interface).

If you want to connect your sensor with a longer wire, you can add a pull-up resistor. If it is only used within a short distance, you don't need it. Detailed information can be found in the AM2302 datasheet.
