Technical data:
Description:
Combined temperature and humidity sensor AM2320 The digital temperature and humidity sensor is a digital signal outlet that was calibrated. The use of a special technology for the temperature and humidity record guarantees a very high reliability and excellent long -term stability of the product. The sensor consists of a capacitive humidity and a high -precision temperature meter integrated and is connected to a high -performance microprocessor. The product is characterized by excellent quality, super fast and a strong anti-interference capacity.
Characteristics:
The voltage conversion sensor module is DD4012SA, a highly efficient voltage converter with low heat development.

The temperature and humidity sensor is AM2320.
RTU protocol, 03 Read, 06 Write.
Generated for dehumidifiers, test and inspection devices, automotive industry, automation, service stations, appliances, humidity control, relevant measurements and humidity controls and other relevant.
Technical data:
Work voltage: DC 5-40 V (6.5–28 V recommended)
Working current: turning off the digital tube is 5 m -(12 v), the lighting of the digital tube is 18 mA (12 v)
Serial Baud Rate: 9600 (standard), N, 8, 1
Wear:
1, show "error" after turning on.
If "eror" is shown for a long time, this indicates that the sensor is not connected or damaged.
2, after 5 seconds the temperature or moisture is shown.
3, press the "key" button to change temperature and humidity display. (This parameter is off).
4: Keep the "key" button pressured for 3 seconds to turn on the screen. (This parameter is also switched memory).
Note: If the digital tube turns off after turning on, hold the "key" button until the digital tube is on.
Wiring plan:
A notice:
With the built -in, with the sensor version (R444a01_A), the temperature can increase by 1-2 degrees Celsius when lighting the screen for a long time. It is recommended to turn off the digital tube or use an external sensor (R444A01_B).
Keep in mind that the new type and old type of this product will be sent randomly and make sure you don't care before ordering.
Package Included:
