    I have some insertable switch boards without radio. I planned to solder nrf24 into them but can sell them without radio too (it supports only cw modules). Will put up for sale soon.

    @Koresh Sounds great! Oh and btw, any idea how customs will handle the packages, any chance of taxes and customs fees? You're outside of the EU customs union right?

      @bjornhallberg I do not know exactly, but I don't think there should be any fees. Try to find out tomorrow.

        @Koresh I got one of boards and would like to add Si1132-A10-GMR. What else I need to add? C8?
        Why are you not using this sensor on your board?

          @alexsh1 yes, you should solder the sensor and the bypass capacitor. I have a lot of si1132 sensors, but I can't find the correct library. Almost promo videos of commertial sensors based on the si1132 shows incorrect data ))) It shows correct UV and IR level, but incorrect visible light value. So I decided to not solder this sensor yet.

            @Koresh I would only use it for UV so this is good for me.

            No need to use a lib:

            // Use it any way you want, profit or free, provided it fits in the licenses of its associated works.

              @Koresh BTW, Found this library - working fine for my needs

              https://github.com/hardkernel/WEATHER-BOARD/tree/master/libraries/ODROID_Si1132

              I am using this sensor purely for UV Index.

              PS Got your sensor. Soldered it to the mote. Works just fine

                @alexsh1 yes, you should solder the sensor and the bypass capacitor. I have a lot of si1132 sensors, but I can't find the correct library. Almost promo videos of commertial sensors based on the si1132 shows incorrect data ))) It shows correct UV and IR level, but incorrect visible light value. So I decided to not solder this sensor yet.

                @Koresh I can see Si1132 visible light is twice more than BH1750.
                Not sure what's wrong, but as you said it reports incorrect value.

                UV Index is in line with VEML6070

                  The sensor looks more complicated that I thought:

                  2.2. Ambient Light
                  The Si1132 has photodiodes capable of measuring both vi
                  sible and infrared light. Howe
                  ver, the visible photodiode
                  is also influenced by infrared light. The measurement of illuminance require
                  s the same spectral response as the
                  human eye. If an accurate lux measurement is desired, the
                  extra IR response of the vi
                  sible-light photodiode must
                  be compensated. Therefore, to allow the host to make corrections to the infrared light’s influence, the Si1132
                  reports the infrared light measurement on a separate channel. The separate visible and IR photodiodes lend
                  themselves to a variety of algorithmic solutions. The
                  host can then take these two measurements and run an
                  algorithm to derive an equivalent lux level as perceive
                  d by a human eye. Having
                  the IR correction algorithm
                  running in the host a
                  llows for the most flexibility in adjusting for system-dependent
                  variables. For example, if the
                  glass used in the system blocks visibl
                  e light more than infrared light, the
                  IR correction needs to be adjusted.

                  I will have to spend more time to understand how to extract the correct ambient light

                      The sketch I posted above contains some errors
                      (it sets COFFs 0x29, 0x89, 0x02 and 0x00 to the 0x13, 0x14, 0x15 and 0x16 registers).

                      The correct UCOEF values are 0x7B, 0x6B, 0x01, and 0x00

                      The sensor is quite complex.

                        I got the following values from the sensor:

                        1. V_VOLTAGE (3.21)
                        2. V_HUM (51
                        3. V_TEMP (30)
                        4. V_LIGHT_LEVEL (4466)
                        5. V_UV (1.74)
                        6. V_LIGHT_LEVEL (3367)
                        7. V_LIGHT_LEVEL (3367)

                        Clearly, Si1132 is not in line with BH1750. VEML6075 is giving me UV Index 1.65, which is close to the Si1132.

                        Moreover, depending where it is used, the coeff in formula has to change (I am using 0.282 for the direct sunlight) :

                          @Koresh My 2032 died in 2 days and I noticed that power consumption is 3.5mA. OK, maybe bad soldering - I desoldered Si1132, but the consumption is still 0.14mA while sleeping. For 2032 this is a huge consumption. Did you measure consumption at all? I am using CW radio

                          Si1132 must be consuming around < 500 nA standby current according to the datasheet. Not sure why consumption was increased with Si1132.

                              @Koresh I did it on the first day I got the sensor. The consumption above is with BH1750 in the sleeping mode as per your github

                                Could you post the code you use? and links for the libs. we will check tomorrow consumption with your code . mysensors 2.0 or 2.2?

                                    @yury One thing I did notice is this. To put BH1750 into a sleep mode (1uA consumption), it has to be called as follows:

                                    void setup()  {
                                    lightMeter.begin(BH1750_ONE_TIME_HIGH_RES_MODE);
                                    
                                    }
                                    

                                    After a one time measurement it goes to sleep automatically.

                                    I have tried above, but still getting 0.14mA consumption in a sleep mode. Very odd!

                                      @alexsh1 Very strange. I can't see a method write8 in current lib version (https://github.com/claws/BH1750). So I can't understand how is it possible to compile default code with this string

                                      lightMeter.write8(BH1750_POWER_DOWN);
                                      

                                      I couldn't put this sensor into power down mode without this.

                                        I've read the claws library briefly again. I'm a litte doubt that this code:

                                        _delay_ms(10);
                                        

                                        is enough to ensure correctly timings and sensors work :)

                                          @Koresh It does work, I have just test it, but there is a delay, i.e. the sensor is lagging one reading behind.
