The 12v Psu is powering an Rgb led strip and a 12v solenoid. These are controlled with a buz11 mosfet using the Wemos D1 Mini. The 12 v coming from the psu is converted to 5v which is connected to the 5v input on the Wemos. The sensor is connected to the 5v from the buck convertor. Maybe I should try to connect it to the 3v3 pin on the Wemos?
