Product Description




The FST100-2201 louver structure multifunctional integrated sensor is a special sensor designed for environmental
monitoring in the process of weather or agricultural production. The built-in core sensors are all imported devices.
The instrument can continuously monitor one or more of the environmental parameters such as carbon dioxide gas
concentration, illuminance and ambient temperature and humidity, and each parameter value is converted into a
MODBUS-RTU standard electrical signal and transmitted to the associated equipment.
