I have some assembled boards without the radio. You can buy them here https://www.ebid.net/eu/for-sale/arduino-ide-compatible-coincell-powered-controller-ready-for-rfm69cw-hcw-radio-156711327.htm . I just reminding this board has a rfm69HCW footprint but you can solder rfm69CW modules with the pcb adapter which I made. Of course I will supply the adapter with the main board.@Koresh Thanks! Great solution with the adapter board as well, you really do think of everything. Do you have the other boards without radio as well? Specifically the Switch Controller?

@bjornhallberg
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. -

@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.

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:
- V_VOLTAGE (3.21)
- V_HUM (51
- V_TEMP (30)
- V_LIGHT_LEVEL (4466)
- V_UV (1.74)
- V_LIGHT_LEVEL (3367)
- 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) :
Visible Photodiode Response Sunlight ALS_VIS_ADC_GAIN=0 VIS_RANGE=0 — 0.282 2500K incandescent bulb ALS_VIS_ADC_GAIN=0 VIS_RANGE=0 0.319 “Cool white” fluorescent ALS_VIS_ADC_GAIN=0 VIS_RANGE=0 0.146 -
@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.

@alexsh1 Do not forget put BH1750 into sleep mode. Unfortunatelly standart library do not put the sensor into this mode. I described it on the github page.
/* Please comment out private declaration in BH1750.h * Otherwise you can't call lightMeter.write8(BH1750_POWER_DOWN); and BH1750 will not sleep! * * //private: * void write8(uint8_t data); */ lightMeter.write8(BH1750_POWER_DOWN); -

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 It is the latest bh1750 lib -> https://github.com/claws/BH1750

I am using a default code :

@yury It is the latest bh1750 lib -> https://github.com/claws/BH1750
I am using MySensors 2.2.0b
I am using a default code :
https://github.com/EasySensors/ButtonSizeNode/blob/master/ButtonSizeNode.ino@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.
Please see -> https://github.com/claws/BH1750/blob/master/examples/BH1750advanced/BH1750advanced.inoI have tried above, but still getting 0.14mA consumption in a sleep mode. Very odd!

lightMeter.write8(BH1750_POWER_DOWN);I couldn't put this sensor into power down mode without this.
