zw3100 data sheet
My question is not directly related to microcontrollers. I’m posting this question here, because you, guys, have seen a lot of instrumentation in your travels.
I’m looking for a wireless remote measurement system that communicates at 433MHz or lower frequency. FCC compliance is not a problem, because it will be working for one month, and it will be shielded from the outside world by a chainlink fence.
The purpose of the system is to measure and transmit gas pressure few times a minute for a month. The range is 50 to 100 meters. 4 or 6 units per base station. Of course, I can add my own pressure sensor to a system that has an A/D.
I’m looking for something that’s pretty small – about the size of a 9V battery
I guess, I could put such system together myself, but I’ve got a very short notice, and I will need to field this system very soon.
Could anyone recommend?
Thanks,
Nick
