I will install my sensors in some closed industrial metal box and I will install this somewhere outside. The idea is to install the "air sensors" in a single conduit, a short tube is pointed downward in order to keep rain outside and the entrance covered with some gross filter in order to keep insects outside, first comes the PT1000 T° sensor and the humidity sensor and after this the particle counter is connected to this tube, this sensor has a fan inside and I will use the suction of this fan to create a slow air flow for the T° sensor, after the particle sensor comes the CO2 sensor. Another down pipe is the outlet. The baro has a separate input as putting it in the main "input" will distort the readings because of the fan. See pic. The light and UV sensors are a bit more complicated, the ambient light sensor will have a simple acrylate matte dome but the UV's will be installed in a separate window that is made from several layers (min. 0,5 mm) of PTFE (Teflon) gasket tape. This tape has a good transmittance of the total UV range, professional sensors are also made with this. The idea is to install these light sensors slightly oblique and according to the ecliptica so there will be a better reading facing the sun. I may install an overall polished stainless shield around in order to keep the electronics cool in summer. Hope this helps! Jacques

That would be nice bevause i really do not know, how and where to install my sensors. The BME280 is no problem, but the VEML6075, TSL2591 and the particle sensor. They need light or air but no water. ;) So ideas where to install them are appreciated.

Hello, I just finished mounting all elements end carefully followed all of the nice assembly manual (except serial settings). I have powered the circuit with a 9V 300mA adapter. But after one hour I see only 00.00 µSv/h. With the "select" button, and "Buzzer & Led On", I  can hear the radiation detections and see the led blink. But the Count CPM stay 00000. Is there some minimum settings to do before mesuring any radiation ? Or where I am wrong ? Best regards Dominique
