Description:
Temperature and humidity combined sensor AM2320 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.
Specifications:
Working Voltage: DC 5-40V(6.5-28V recommended)
Working Current: Digital tube turn off is 5MA(12V), Digital tube turn on is 18MA(12V)
Serial Baud Rate: 9600(default), N, 8, 1
How to use:
1. Display “Eror” after power-on.
If “Eror” is displayed for a long time, it indicates that the sensor is not connected or is damaged.
2. After 5 seconds, display the temperature or humidity.
3. Trigger “KEY” button to switch the display temperature and humidity.(This parameter is powered down memory).
4. Press and hold the “KEY” button for 3 seconds to turn off or turn on the display.(This parameter is also powered down memory).
Package Includes:
1 × Module
1 × External Sensor
Note:
1. If the digital tube is turn off after power-on, press and hold the “KEY” button until the digital tube is turn on.
2. With the built-in sensor version (R444A01_A), turn on the display for a long time will let the temperature rise 1-2 degrees Celsius. It is recommended to turn off the digital tube, or use a version with an external sensor (R444A01_B).
