Hi,
I'm working on a project about cold chain monitoring in food transportation. The project has only two requirements: use very cheap sensor (<= 20$ per unit – this is a very strict requirement) and short range of sensor/receiver (about 50~100 meters in open space). I'm looking for a complete low-cost solution composed by RF temperature sensors and receiver. Moreover, I need to interface each receiver to a single board computer (SBC) via RS232 interface, in order to log data and send analysis to a data center through GPRS communication.
Do you think that I have to build a custom solution (maybe using zigbee?!?) or there are ready to use solution available on the market?
Your help is very appreciated. Thanks in advance
