Reduce wiring work in office buildings and use it for measuring "temperature," "temperature and humidity," and "CO2 concentration."
In the case of measuring temperature, humidity, and CO2 concentration in large spaces such as offices, shopping centers, and arenas, using wireless sensors can reduce the need for wiring work. Up to 32 wireless sensors can be placed for one receiver. 【Features】 - There are sensors that operate solely on indoor lighting as their energy source (battery-less). - Sensors with auxiliary battery specifications can transmit measurement data at a faster interval. - There are CT clamps for power (single-phase) (three-phase) for measuring current values. - The receiver supports Modbus RTU communication, allowing multiple communication connections. - All wireless sensors are easy to install (the CO2 sensor requires a power supply). - Moving the installation location of the sensors is easy (due to rearrangement of office furniture, etc.).
