Product Description:
YJJ AM2302 Temperature and Humidity Sensor Module - Digital Output Order Model Black Module
Features:
I. Product Overview
AM2302 humidity-sensitive capacitor digital temperature and humidity module is a temperature and humidity composite sensor that has a pre-calibrated digital signal output. It utilizes dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure the product has extremely high reliability and long-term stability. The sensor consists of a capacitive humidity sensing element and a high-precision temperature sensing element, and is connected to a high-performance 8-bit microcontroller. Therefore, this product has advantages such as quality, ultra-fast response, strong anti-interference ability, and excellent cost performance. Each sensor is calibrated in an extremely humid laboratory. The calibration coefficients are stored in the form of a program in the microcontroller, and the sensor internally calls these calibration coefficients during the processing of the detection signal. The standard single bus interface makes system integration simple and fast. The small size, extremely low power consumption, and signal transmission distance of up to 20 meters or more make it an excellent choice for various applications and even for demanding application scenarios. The product is connected with 3 leads (single bus interface) for ease of use. Special packaging forms can be provided according to user requirements.
II. Application Scope
HVAC (Heating, Ventilation, and Air Conditioning), dehumidifiers, testing and inspection equipment, consumer products, automobiles, automatic control systems, data recorders, household appliances, humidity regulators, healthcare, weather stations, and other related humidity detection and control applications.
III. Product Highlights
Ultra-low energy consumption, long transmission distance, fully automated calibration, using capacitive humidity-sensitive elements, fully interchangeable, standard digital single-bus output, long-term stability, using high-precision temperature measurement elements.
