The new updated version of the TeHyBug universal 18650 Board is already available at Tindie.
The difference compared to the previous version:
|Old version||New version|
|The previous version of the device utilized an ESP-01 Module that came with 1MB memory. It was straightforward to replace or switch out the module, and could be conveniently flashed with an esp-01 programmer. The device also had a display connector integrated on the board. However, since the ESP-01 Module did not support ADC ports, the previous version lacked any such ports.||The updated version of the device features a soldered-to-board ESP-m1 Module that comes with 2MB Memory. Unlike the previous version, this module needs to be flashed directly onto the TeHyBug board. The device no longer has a display connector on the board as a specially designed TeHyBug Display board is available. However, users can still use the i2c Port to connect a display. The new version includes an ADC Port that enables users to connect soil moisture and other ADC sensors. It’s worth noting that the ADC Port is also compatible with one-wire sensors. Another notable feature is the solar panel connector located on the back of the board. This feature makes it possible to charge the battery using a solar panel.|
We spend over 90% of our time indoors, where the amount of CO2 we exhale has a significant impact on our health and well-being. High CO2 concentrations not only lead to tiredness, headaches and can cause dizziness, they are also a good indicator of when the distribution of aerosols in the air exceeds a value that is more conducive to the spread of coronaviruses. Ventilation therefore reduces the risk of corona infection.
