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.

Product Description:
AM2320 digital temperature and humidity sensor is a calibrated digital signal output containing hexyl temperature and humidity sensor complex. Temperature and humidity using a dedicated capture technology to ensure that products with high reliability and excellent long-term stability. Sensor includes a capacitive humidity sensing element and an integrated high-precision temperature measurement devices, and connected with a high-performance microprocessors. The product has excellent quality, fast response, anti-interference ability, high cost and other advantages.
AM2320 communication using a single bus, standard I2C two means of communication. Standard single-bus interface, allowing system integrators to become simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up to 20 meters or more, 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 directly linked to the I2C communication bus without additional wiring, simple to use. Two means of communication are used as humidity, temperature and check CRC and other digital information directly via temperature compensated output, users do not need to calculate the secondary digital output, and no need for temperature compensation of the humidity, you can get an accurate temperature and humidity information.
