Hi,
I am using a small battery to power both a sensor and a transceiver to send a signal for ~500 meters. I am looking for the lowest power-consuming method. I don't really care about how low my transfer rate. 1 sample per 1 is good enough
For my sensor, I was thinking of using a Thermistor with a load resistor because it is low power.
However, I was not sure what to use for a transmitter:
BLE, LORA, SIGFOX. Also, I probably need something to read my analog to digital too like a processor.
As a whole system:
What is the lowest power approach? Can you recommend a chip?
