product description

AM2321 / AM2322 digital temperature and humidity sensor is a calibrated digital signal output already contains temperature and humidity sensor complex. Using special temperature and humidity acquisition technology to ensure that products with high reliability and excellent long-term stability. Sensor comprises a capacitive humidity sensing element and an integrated high-precision temperature measurement devices, and with a high performance microprocessor is connected. The product has excellent quality, fast response, anti-interference ability, high cost and other advantages.

AM2321 / AM2322 single communication bus standard I2C two means of communication. Standard single bus interface, system integration becomes simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. I2C communication using standard communication sequence, the user can be directly linked to the I2C communication bus, no additional wiring, simple to use. Two means of communication are used as humidity, temperature and CRC checksum and other digital information directly output temperature-compensated, users do not need to calculate the digital output of a second, and no need for temperature compensation of the humidity, you can get an accurate temperature and humidity information. Two means of communication are free to switch, the user can freely choose, easy to use, it should be a wide range of fields. 4 products for lead, easy connection, special packages can be provided according to user needs.

DHT11:

The DHT11 digital temperature and humidity sensor 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 resistive wet sensor and an NTC temperature sensor 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 DHT11 sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. The single-wire serial interface makes system integration easy and fast. Ultra-small size, extremely low power consumption, and signal transmission distances of up to 20 meters make it the best choice for even the most demanding applications. The product is available in a 4-pin single-row lead package.
