What is the difference between AM2311 and AM2321, AM2301 digital temperature and humidity sensor?

AM2311 humidity sensitive capacitor digital temperature and humidity module

 

AM2311 is I2C bus product, which is different from AM2301 with single bus.

It can directly replace SHT10 / SHT11 / SHT15 / sht71 / SHT75 from hardware circuit

Product overview

AM2311 humidity sensitive capacitor digital module is a temperature and humidity composite sensor with calibrated digital signal output.

Using special digital module acquisition technology and temperature and humidity sensing technology, the product has high reliability and excellent long-term stability.

The sensor consists of a capacitive humidity sensing element and a high-precision NTC temperature measuring element, and is connected with a high performance 8-bit MCU.

Therefore, the product has the advantages of excellent quality, super-fast response, strong anti-interference ability and high cost performance.

Each sensor is calibrated in an extremely accurate humidity calibration chamber.

The calibration coefficients are stored in the form of program in the single chip microcomputer, which are called in the process of signal processing inside the sensor.

The standard single bus interface makes the system integration easier and faster. Ultra small volume, 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.

The product is divided into 3-lead (single bus interface) and 4-lead (I2C bus interface) for convenient connection and free choice of any bus mode. Special packaging forms can be provided according to user's requirements.

Product overview

AM2321 Humidity sensitive capacitance digital temperature and humidity sensor is a kind of temperature and humidity composite sensor with calibrated digital signal output.

Special temperature and humidity collection technology are adopted to ensure high reliability and excellent long-term stability of the product.

The sensor consists of a capacitive humidity sensor and an integrated temperature sensor, which are connected by a high performance microprocessor. Therefore, the product has the advantages of excellent quality, super-fast response, strong anti-interference ability and high cost performance.

AM2321 communication mode adopts single bus and standard I2C communication mode.

The standard single bus interface makes the system integration easier and faster. Ultra small volume, extremely 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 mode adopts standard communication timing, users can directly hang on the I2C communication bus, without additional wiring, easy to use. Both of the two communication methods use direct output of digital information such as humidity, temperature and CRC after temperature compensation.

Users can get an accurate temperature and humidity information without secondary calculation of digital output and temperature compensation of humidity.

The two communication modes can be switched freely, and users can choose freely. It is convenient to use and should be widely used.
