ข้อมูล AM2320 เซนเซอร์อุณหภูมิและความชื้นแบบ I2C

AM2320 digital temperature and humidity sensor is a calibrated digital signal output already contains 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 sense element and a wet-precision temperature measurement devices integrated and connected with a high-performance microprocessors. The product has excellent quality, fast response, anti-interference ability, high cost and other advantages.

AM2320 single communication bus standard I2C two means of communication. Standard single-bus interface, the system integration becomes simpler and faster. 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 communicate directly linked to the I2C bus, no additional wiring, simple to use. Two means of communication are used as humidity, temperature and check CRC and other digital information directly by temperature compensated output, users do not need to calculate the secondary digital output, and no need to compensate for temperature and 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 broad areas. Products for the 4-wire, easy connection, special packages can be provided according to user needs.
