My project involves a remote weather station. That's a bit of a grandiose description because, at present, it only returns temperature and humidity readings from a DHT22 sensor. Communication with the home (PRX) station is via radio transmission using an nRF24L01+ breakout. Circuit diagrams and the INO files are attached.
I ran this setup thought the night last night, but in the morning it decided to quit.. It didn't ask permission or anything, it just quit.
Since the hardware, which is breadboard prototyped, remained untouched throughout the whole proceeding I don't think it is a connection coming loose. Anyway, if that were the case the data printout would not show one missed transmission then several successfully received transmissions.
Suspicion falls to the radio transmission, and therefore on the transmitter/receiver chips. I have used them in the past and always considered them reliable - but they are suspect at the moment.
Can anyone suggest another cause of the halted test run?
Is the nRF24L01+ not completely reliable?
Is there a better alternative?
