✨ 3Pcs DHT22 AM2302 Digital Temperature and Humidity Sensor Module ✨🔍 Product Overview
Model: AM2302 Humidity Capacitor Digital Temperature and Humidity Module
AM2302 Humidity Capacitor Digital Temperature and Humidity Module is a temperature and humidity composite sensor with calibrated digital signal output.
It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and excellent long-term stability.
The sensor includes a capacitive humidity sensing element and a high-precision temperature measuring element, and is 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 extremely high cost performance.
Each sensor is calibrated in an extremely precise humidity calibration room. The calibration coefficients are stored in the microcontroller in the form of a program, and these calibration coefficients are called in the sensor during the processing of the detection signal.
The standard single bus interface makes system integration simple and fast. Ultra-small size, extremely low power consumption, and signal transmission distance of more than 20 meters make it the best choice for various applications and even for demanding applications.
The product is 3-lead (single bus interface) for easy connection.
Features: ultra-low energy consumption, long transmission distance, fully automated calibration, capacitive humidity sensor, fully interchangeable, standard digital single bus output, excellent long-term stability, high-precision temperature measuring element.
