Our company needs wireless temperature sensors (can be externally powered or battery operated) and transceiver with 4 channel analog outputs. It has to be finished product.
The distance of communication is desired to be 100 to 200 meters if possible. Up to 4 RF temperature sensors will be located in a building and there will be a single transceiver. 4-Analog output voltages of the transceiver can be 0-5, 0-10 or 2-10, any DC voltage that will reflect - correspond to the reading of the temperature sensor.
The sensors may be coded as sensor 1, 2, 3 and 4. They can correspond to transceiver analog outputs 1, 2, 3 and 4. Transceiver analog outputs will be hard wired in to a dedicated controller which has universal inputs.
Any feedback is appreciated. Thank you.
