Click on "monitor", we can see 1 # sensor temperature value of channel 1 in the software, exit "monitor", click the "parameter
upload", then you can view the serial numbers of the sensor. Read 1 # sensor temperature value and serial number as shown
below:
Numerical 251 indicates that the current temperature is 25.1℃;

is, -550 ~ 1250) when the sensor is not connected.
Then we access the second sensor (for the strict wiring diagram, please refer to the above digital module wiring diagram), the
access interval time of adjacent sensors should be greater than 10 seconds. Wiring diagram is as follows:
