Sensor Categorization
As shown in the image, the sensors are divided into two categories: (1)"Custom sensors” and (2) "built-in support"
sensors.
5.1.1 Custom Sensors
Sensor Hub Data Logger supports connecting to the standard Modbus-RTU sensors that meet the following
specifications:
Access Protocol
Standard Modbus-RTU RS485 protocol
Modbus Address
[128，254] (Decimal)
Function Code
03/04
Power Supply
5V or 12V
Working Mode
wake-up(Periodic) mode / normal constant power(Always-On) mode
Measurement
Range
Formula: y = a*x + b (x is the measurement value).
The values calculated according to the formula must be in the range of -20000000000 to
+2000000000
5.1.2 Built-in-Support Sensors
Sensor Hub Data Logger has built-in configuration information for the SenseCAP Modbus-RTU RS485 sensors series
(by default). And you can configure to enable or disable this function.
When connected to a SenseCAP Modbus-RTU RS485 sensor, users do not need any configuration, just plug and play.
SenseCAP sensors are industry-standard sensors, suitable for outdoor applications scenarios such as agriculture,
cities, industry, and more.
