Precise enough for my HVAC lab work

Man, this little Humidity Probe is surprisingly accurate. I’m getting consistent ±0.3°C readings on the temp side. The Modbus-RTU protocol is standard, so no headaches there. Wish the mounting bracket came in the base price instead of being an add-on, but the High Temperature performance of this sensor is worth the extra ten bucks. Just get it.
