6.5 Configure Analog Sensor via App
Select the “Protocol as Analog input”. Then set the following parameters in turn.
Power Type
Periodic power: Power the sensor before data collection, and power
off the sensor after data collection. This mode reduces power
consumption and increases battery life.
Always-on: Select this mode when the sensor needs constant
power supply. Generally, an external 12V DC power supply is used.
If it is powered only by batteries, it may not work for long.
Power Voltage
Select the supply voltage to the sensor. It supports 3V/5V/12V.
Please refer to section "Power Supply Options of Sensor".
Analog Input
Current: Select the current signal of the sensor from 4 to 20mA.
Voltage: Select the voltage signal of 0~10V sensor.
6.5.1 Set the 4~20mA sensor
Sensor Warm-up Time
The warm-up time denotes the amount of time it takes for the
sensor to attain its highest accuracy or performance level once the
voltage supply has been applied.
Current Range
4~20mA
