Newbie - Proximity Help

Hi all
I am new to all this stuff so hope you can help, I am looking for a Proximity sensor that is 12V and water proof but struggling to find anything that would match what I need can anyone help or point me in the right direction please

1: 12V for a car or truck
2: needs to be water proof
3: able to adjust the distance accordingly to where we need it
4: when within the correct distance of activation it will need to turn a LED light on or similar

Once I have found the correct sensor I should be able to make up a circuit but it's finding it

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

Some humidity sensors are known to lose accuracy with age. For instance, the Si7021 is known to have this problem. If that matters to you, then the best choice is to pick sensors that have datasheets and which have specs as to their expected longevity or accuracy over time. Then buy from mouser/digikey to be certain you're getting the real thing rather than factory rejects or counterfeits. For extra insurance, I avoid electrolytic capacitors entirely whenever possible. I buy only 7XR rated ceramic capacitors that are overspec'd. The difference in price is small compared to a failure down the road.

Hi everyone Which MySensors lib did you use? The 2.3.2 or the delevopment version? I tried to fix the errors, but they don't appear in the development branch. Only another error which i fixed. Regards, Edi

hey @dirkc, maybe you can trigger your interrupt to rising and falling edge and use millis() to see how long the press was?

@skywatch said in Awesome tip: run LinuxFX instead of Windows!: @NeverDie Thanks - Interestingly they show a free version on their site still. Did they revert due to bad publicity? https://www.linuxfx.org/ I stopped following it, but I seem to recollect that the free version was noticeably missing things--otherwise, who'd buy the paid-for version? Anyway, its standing on Distro-watch has fallen considerably. It may seem unfair to niche distros, but I think it's generally better to stick with the more popular distros, unless you have good reason to choose otherwise.

@OldSurferDude My old 2.0 setup is with nRF24L01 radios. This is a link to the thread on some light switches that I designed and built. https://forum.mysensors.org/topic/7376/us-decora-wall-switch-continued/2 I am aware that you cannot have two MQTT gatways. When I designed my old setup I was not that familiar with MQTT so I never ended up implementing it. On the home assistant server that I have set up though, I have installed the MQTT broker on there so I should be able to comunicate with any MySensors stuff over MQTT in the future devices I make/set up. As I mentioned, I do have a Home Assistant box that I have started about 4 months ago and eventually want to migrate my Vera equipment to the HA box. As for the YAML and Python, I'll muddle my way through. used to program in PHP and have done enough on Arduino that I'm sure it won't hurt my brain too much.
