I got some emails from people interested in buying the device, and here are the details in the bellow table. Please note that I do not make this device for mass production and the bellow prices are considered fair for the efforts I need to invest in organizing ordering and building the devices. If you build it yourself it will cost about half these prices with most of the parts from China stores like Aliexpress.
Note 1 Oct 2021: I stop producing fully assembled devices. I need focus on another things to do and I am very limited with time to keep the stock of parts. Also the prices of components is constantly increasing and some of them difficult to find. I will continue with making the fully assembled PCBs with all the parts until I have components in stock and eventually until there is interest. Also I have some available BME280 breakout boards which I assemble myself.
| Item | Price (EUR) | Notes |
|---|---|---|
| PCB only | 5 | You have to order and solder all components yourself. |
| Fully assembled PCB without sensors, but including the ambient light senor | 35 | with high quality Samtec receptacles and Omron switches. You have to order all the other components yourself and solder the MH-Z19 sensor on the PCB. |
| BME 280 breakout board | 8 | These boards are 4 pin, only I2C and only 3.3V compatible with the board, i2c address can be changed. I assemble them myself as BME280 is difficult to get from Aliexpress. |
| Case holder, PETG material | 7 | color orange only at the moment (like on the photo) |
* I do not provide completely assembled board with SGP30 TVOC sensor anymore because of the poor quality of these boards (explained here), you can buy yourself this board if TVOC is needed.
These prices exclude shipping. If you are interested in ordering, please send me an email to [email protected] with your address and I will let you know when the device can be ready as I might not have all parts.
Shipping is 7 EUR for one device with registered post, there are other faster options upon request. Payment is with bank transfer (preferably), Paysera (EU paypal similar service, also preferably) or Paypal. With Paypal if you are non EU account, I will add 2% as they charge me extra Cross border fee.
Please note that due to semiconductor shortage BME280 breakout boards are difficult to find (June 2021) and they are more expensive. I am currently using my own breakout where I solder the BME directly. These are a bit smaller in size than the BME breakout from China. BME280 as IC can be found occasionally in stock from DigiKey.
You can see the device also in the video, also in this video is shown how to complete the device with assembled PCB.
