The Lux & Air Sensor is a 4-way sensor. For lux, humidity, air pressure and temperature. And to connect it to a PLC it has 0-10V outputs.

I made this sensor board for myself because I needed a Lux sensor with a 0-10V output for my home automation with Siemens LOGO's. And since the OP AMP has 2 outputs anyway, I decided to also use a 2-way DAC. And to put the Bosch combi air sensor on the board in addition to the Lux sensor.

The Rohm HB1750 Lux sensor and the Bosch BME280 humidity & air pressure sensor are used as sensors. The LM358 OP AMP is used as the output. Which is controlled by the MCP4922. The ATmega328P is used as a microcontroller. Jumper can be used to determine what the two outputs output.
You can choose from:
0 - 600 lux
0 - 3000 lux
600 - 10,000 lux
0 - 100% rH
300 - 1100 hPa
-25 - 55 °C
0 - 50 °C

Without a jumper, the sensor board is in debug mode. That means: output 1 gives 0 - 600 lux and output 2 outputs -25 - 55 ° C. And under 100 lux the LED starts to shine.
