TC-08 with PC Board connect Humidity Sensor
Hi All
I'm try to connect a humidity sensor to the PP624 Board. I have the following issues.
1.I have a analog humidity sensor with 0-5 VDC output
2. Is the 5V input AC +5 Volt or DC +-5 Volt, there is inconstancy of the labeling and information
3. I had a cheap plug in transformer that put out 5.25 VDC 1 Amp max I purchased a Meanwell LRS-75-5 which will deliver exactly 5 VDC 14 Amp max, when i connect it the the new transformer the sensors now work better and humidity numbers match.
4. The issue is that now the other K Type sensors double in value, if conenct a second humidity sensor the valve doubles again(4x). The the voltage all checks out into the TC-08 PP624 Card (I'm just using a Klein multi meter)
Any help is much appreciated or links to how on how to wire this up correctly.

Re: TC-08 with PC Board connect Humidity Sensor
Hi All
Quick update what seems to be the problem is that the new transformer is lowering the "signal voltage" inside the TC-08. The "cheap transformer" signal input voltage(what show on the PC Screen) matches the test meter voltage. The Meanwell LRS-75-5 signal input voltage(what show on the PC Screen) is lower pico log voltage
Input Onscreen Reading
Meanwell LRS-75-5 2.83 VDC 1.62V
D Link Transformer (Cheap) 3.47 VDC 3.49V
