Am2322 product description
Am2321/am2322 digital temperature and humidity sensors are calibrated digital signal outputs and already contain temperature and humidity sensor complexes.Special temperature and humidity acquisition technology is adopted to ensure high reliability and excellent long-term stability.The sensor includes a capacitive humidity sensor and an integrated high-precision temperature measuring device, which is connected to a high-performance microprocessor.The product has the advantages of high quality, fast response speed, strong anti - jamming ability and high cost.
Am2321/am2322 single communication bus standard is i2c two modes of communication.Standard single bus interface, system integration becomes simpler and faster.Ultra-small size, low power consumption and signal transmission distance up to 20 meters make it the best choice for all applications and even the most demanding ones.I2c communications use standard communication sequence, users can link directly to i2c communication bus, no extra wiring, simple use.Both communications are used as digital information such as humidity, temperature and crc checks and balances, directly output temperature compensation, and users can obtain accurate temperature and humidity information without having to calculate the digital output for a second, nor do they need humidity compensation.Both modes of communication are free to switch, users are free to choose, easy to use, should be a wide range of areas.The 4 products are easy to connect and can provide special packaging according to the user's needs.

Dht11:
Dht 11 digital temperature and humidity sensor is a composite temperature and humidity sensor with calibrated digital signal output.It uses dedicated digital module acquisition techniques and temperature and humidity sensing techniques to ensure high reliability and excellent long-term stability.The sensor includes a resistance wet sensor and a ntc temperature sensor connected to a high performance 8-bit microcontroller.Therefore, the product has the advantages of high quality, fast response speed, strong anti-jamming ability and high cost-effective.Each dht 11 sensor is calibrated in an extremely accurate humidity calibration room.Calibration coefficients are stored as programs in otp storage and are invoked internally during processing detection signals.Single - line serial interface makes system integration easy and fast.Ultra-small size, extremely low power consumption and up to 20 meters of signal transmission distance make it the best option for the most demanding applications.The product is encapsulated by 4 pin single row lead line.
