G’day. Tyler, automation engineer in oil and gas, based in Australia.
Side project at work: a handful of small wellhead shelters with nothing in them but a pressure transmitter on 4-20 mA and a lot of heat. I want temperature and humidity in each shelter, the pressure reading, and an alarm when any of it goes silly. Boards are MKR WiFi 1010s for now because that’s what was in the cupboard. I’ll report back on how it goes.
Welcome Tyler. How are the shelters getting back to you, cellular?
Yep, a 4G router in each one. Signal is fine at most of them, marginal at two.
Hello from another field person. Watch for condensation in shelters like that, it settles on bare breakout boards overnight when the temperature drops. Conformal coating and a vented enclosure got rid of a lot of strange readings for me.
