Nimomo Capacitive Proximity Switch Normally Open Auto Leveling Sensor Capacitive Detection Switch for 3D Printer ET4 series, for ET4, 4 Pro

I bought this for my model railway (housed in a summerhouse) to detect a train at the station. It works ok, but the proximity/sensitivety changes with ambient temperature. When I set it up at ambient 15 degree, it was fine, but during a spell of higher than average temperatures for this time of year, I had to re-adjust the sensitivety as when the temperature rose, the sensor on its original setting came on all of the time (ambient 21 + degrees) . I have since adjusted it for a high temperature, but results in a lower sensivitey distance at lower temperature. so be aware.
