The MER10 Smart LoraWan Humidity and Temperature sensors and Touchscreen User Interfaces have been designed for measuring room humidity and temperature in modern buildings. The MER10 LoraWan sensors can have additional PIR occupancy sensor for movement indication and control. With LoraWan option the sensors can connect wirelessly to IoT or Building Management Systems.

The sensors have 2 x Universal Inputs (NTC10 resistance, 0-10V and digital), 4 x 0-10Vdc outputs and optional 24V relay output. The outputs can be used to send the measurement signals to BMS and other building controllers. The measurement signals can be scaled to match the controller input ranges. The inputs and outputs can also be controlled over the network, making the device operate as intelligent BACnet I/O-module.

The colour touchscreen converts the smart sensor to operate also as the Room User Interface Panel. The sensor can display measurements and energy readings, as well as it can be used to change the system setpoints, override the boost (timed) on/off, configure the fan speed levels and the operating modes. The display can be locked from unauthorized use. 

The smart sensors also incorporate 2 x PI control loops that can be used e.g. to provide single stage heating/cooling/humidity/dehumidify control.

The touchscreen skin colours can be changed to suit the building decor. In addition the smart sensors are available in black and white. The sensors are mounted on the wall surface directly or to standard wall mounting boxes. The sensors have additonal built-in Modbus MS/TP communication that can complement the LoraWan wireless communication to the BMS systems (Building Management Systems). 

The MER10 LoraWan sensors can be configured using Windows Device Configuration Tool (connected wirelessly using Bluetooth) or from SmartConfig iOS app. For ease of commissioning the sensor address can also be set from the bit switch or from the touchscreen.
