RHF1S020HHS

LoRaWAN Office Health VOC , Temperature, humidity, air quality sensor

RHF1S020 Series sensors are designed for indoor intelligent building and Healthy Home applications, it features excellent wireless coverage with LoRa technology, easy to deploy. This documentation describe the detail specification of Home Health Sensor.

Home Health Sensor device includes a Temperature Humidity sensor and a Volatile Organic Compound sensor. The VOC sensor requires the first sensor Temperature Humidity to compensate for its operating conditions. The ideal using case is to place the sensor in a room to detect temperature, humidity and if the air quality is in good range.

The sensor measure the Temperature Humidity,CO2 and Volatile Organic Compound data, transmit to a LoRaWAN network.

Applications

Home Air quality measurement
Office Air quality measurement
Warehouse Air Quality measurement
Hospital ari quality measurement.
Intelligent Building
Energy saving

Air quality sensor

Air quality sensor will measure the Volatile Organic Compound in the air with its sensor inside, and then calculate the relative CO2 and VOC concentration, this data is based on the change against the background , so the value maybe different according to the background air condition when it is starting up.

The table below shows the common air quality Class, and default threshold setting in RHF1S020HHS.
