Features and advantages
l Modbus RTU protocol.
l Supports one-way temperature acquisition, and retains one decimal digit when the acquisition result is displayed on the screen in degrees Celsius (℃). The measurement range is-20.0~75.0℃, and the typical accuracy is ±0.3℃@25℃.
l Support one-way humidity collection, and retain one decimal number when the collection result is displayed on the screen, expressed as percentage (%)%. The measurement range is 5~95% RH, and the typical accuracy is ±3.0% (20-80%RH@25℃).
l Supports one-way dew point temperature acquisition, and retains one decimal digit when the acquisition result is displayed on the screen in degrees Celsius (℃). The measurement range is-40.0~75.0℃, and the typical accuracy is ±0.3℃@25℃.
l Allows you to customize the upper temperature and humidity alarm threshold, and allows you to customize the lower temperature and humidity alarm threshold. When the specified threshold is exceeded, an alarm point value is generated.
l Supports mechanical button Settings.
l Support the button to light up the screen (backlight) function.
l Support rapid temperature and humidity rise and fall.
l Supports connecting RS485 serial port for upgrade.
Brief introduction
Temperature and humidity sensors are suitable for monitoring the environment of data center rooms, micro modules, enterprise rooms and other places that need to monitor the ambient temperature and humidity.
Interface specification
Note: The first and second power supply and power supply/communication and communication interfaces are connected in parallel to facilitate hand-in-hand wiring.
