 AM2321
1. Product overview
Temperature and humidity combined sensor
AM2321 digital temperature and humidity sensor is
a digital signal output has been calibrated. Using
special temperature and humidity acquisition
technology, ensure that the product has a very high
reliability and excellent long-term stability. Sensor
consists of a capacitive moisture element and an
integrated high-precision temperature measurement
devices, and connected with a high-performance
microprocessor . The product has excellent quality,
super fast response, strong anti-interference ability,
very high property price rate.
AM2321 communication using a single bus, two communication modes standard I 2 C. Standard
single-bus interface, the system integration becomes easy and quick. Ultra-small size, low power
consumption, signal transmission distance up to 20 meters, making all kinds of applications and even
the most demanding applications the best choice. I 2 C communication using standard communication
sequence, the user can directly linked to the I 2 C communication bus without additional wiring,
simple to use. Two communication modes are used as humidity, temperature, and other digital
information directly CRC checksum temperature-compensated output, users do not need to calculate
the secondary digital output, and no need for temperature compensation of the humidity, temperature
and humidity can be accurately information. Two communication modes are free to switch, the user
can freely choose, easy to use, wide range of applications. 4 lead product, easy connection, special
packages according to user needs and provide.
2. Applications
HVAC, dehumidifiers, testing and inspection equipment, consumer goods, automotive,
automation, data loggers, gas stations, home appliances, humidity control, medical, and other
relevant humidity measurement and control.
3. Product Highlights
Completely interchangeable, low-cost, long-term stability, relative humidity and temperature
measurement, long distance signal transmission, the digital signal output, precise calibration, low
power consumption, standard single-bus digital interface standard I 2 C bus digital interface,
communication free choice.
