Pressure Sensor

damato300x7

Is there a way to hook up a pressure sensor to Uni. I want to put it on my pool filter measure the pressure as it rises to see when i need to back flush the pump. I would like to add a temp sensor on it as well, that seems pretty straight forward but cant find any documentation on a pressure sensor. Ive bought a pressure sensor from seeed studios. Here is a link to it.

thanks for any help

Hi,

yes it shoud work.

Feed the UNI with +12-36VDC (VCC red) and 0VDC (N black).

Feed the SENSOR VCC (red) with +5VDC

Connect the SENSOR OUT (blue) to UNI ADC_in (white)

Connect the SENSOR GND (black) to UNI INTERNAL GND (green)

For temperature you can use up to three one wire sensors type DS18B20

I use someting similar with one sensor for tank-level and two temperatur sensors...

hello can you help me in connection

like > DS18B20 lines what color you give to shelly, while the green already connected to black for tank sensor.

and do i need to feed the unit also 5v pulse 12v??

pressure sensor already working .. need to connect DS18B20

the pressure sensor will not output more than approx. 3V
Anbage manufacturer is 5V DC, not 3.3V DC
Factor: Vout = VCC x (0.75 x P + 0.1), P is Pressure.
