My application is to transmit sensor data wirelessly about 40 feet. The remote sensor will be powered by a small solar cell and a 4 Farad capacitor to allow continuity of operation when the sun goes behind a dark cloud. So the sensor circuit must draw as little as possible. I was using an HC12 433 MHz transceiver module but that draws about 100 mA. which is too much. I see that the nRF24L01+ module draws about 8 mA. on average when transmitting.
My sensor chip can be easily set to output data once every second over the I2C interface. Is it possible to connect this directly to the nRF24L01 or other simple RF transciever chip? Has anyone tried this?
