Grove-all in one environmental sensor SEN54 powered is an integrated, superior Grove IIC ambient sensor, assembling PM, VOC, RH, Temperature sensing functionality, delivering up to 7 types of environmental data signal, sensing in high accuracy and operating for long terms, born for HVAC(Heating, Ventilation and Air Conditioning) and air quality long years detecting applications. Powered by Sensirion, it represents fine sensing performance, and there will be only one Grove cable needed between the sensor and the single board, such as Wio terminal, Seeeduino, Arduino expansion board, Raspberry Pi expansion board, and XIAO expansion board, as simplifying the edge in the wild.

Based on the complex mathematical algorithm and model, the sensor has been designed to output calibrated digital signals to ensure superior sensing accuracy. Meanwhile, the sensing components on it possess high robustness which makes it cable of operating 24/7 for up to 10 years. There are three operating modes available for the user, which is helpful for edge deploying. It costs only 6.8 mA under RHT/Gas-Only Measurement Mode and 2.6 mA for Idle Mode while the full function of Measurement mode can be programmed to set on or off through the IIC function.

Imagine you are in a poor air quality environment without knowing it, or you want a device that can detect harmful gases in real-time, that this device can be easily deployed and used, for a way long time applying. Then this Grove-all in one environmental sensor will be the amazed Grove for you
