HR-802 two channels Wireless Analog Acquisition Module
HR-802 Analog Wireless Acquisition Module has the function for
analog acquisition and wireless transmission, do not re-empolder,it
can achieve the function for wireless remote controlling and
collecting data with a low cost. It is industrial design and has a
wide work temperature so that can meet client's requirement for
whole day using. Besides, the RF adopts narrowband FM and has high
anti-jamming. Accord with EN300220.
