TeHyBug

Mini weather station with WIFI connectivity.

A temperature and humidity sensor at home serves several purposes:

Comfort: It helps maintain a comfortable indoor environment by allowing you to adjust heating, ventilation, and air conditioning (HVAC) systems according to temperature and humidity levels.

Health: Monitoring humidity levels can prevent mold growth, which can cause respiratory issues and allergies. Additionally, maintaining optimal humidity levels can help alleviate dry skin and respiratory irritation.

Energy Efficiency: By accurately measuring temperature and humidity, you can optimize HVAC settings to reduce energy consumption and lower utility bills.

Protection of Belongings: Certain items like musical instruments, artwork, and electronics are sensitive to humidity levels. Monitoring and controlling humidity can help protect these belongings from damage.

Early Warning: Fluctuations in temperature and humidity can sometimes indicate issues such as leaks, poor insulation, or HVAC malfunctions. Detecting these early can prevent costly repairs and damage to property.

I’m pleased to announce that I’ve finally completed the firmware for the TeHyBug CO2 FreshAirMakesSense Boards. These IoT devices are designed to monitor CO2 levels and provide insights into the air quality in your home or office. With the new firmware, these devices are now even more versatile and useful for smart home enthusiasts and DIYers.

The new firmware includes all of the most essential features for smart home integration. One of the key features is the built-in webserver, which serves up sensor data in JSON format. This means that you can easily access and analyze the data using your favorite programming language or data analysis tool. In addition, the firmware includes an autodiscovery mode for HomeAssistant, which makes it easy to integrate the devices with your smart home setup.

But that’s not all – the firmware also includes support for OLED displays, which can be used to display real-time sensor data or other useful information. There are also several other features that are sure to come in handy for DIYers and smart home enthusiasts.

If you’re interested in trying out the new firmware, I invite you to visit the GitHub repository where I’ve published the code. You’ll find a complete list of features and a detailed description of how to install and use the firmware. With this new firmware, the TeHyBug CO2 FreshAirMakesSense Boards are even more powerful and versatile, and I’m excited to see what the community will create with them!

At TeHyBug, we’re always looking for ways to improve and expand our product offerings. That’s why we’re thrilled to introduce our latest innovation – a new, smaller version of our CO2 sensor board.

The new board features the SCD4x sensor, which is smaller than the previous sensor but still maintains the same high level of accuracy and reliability. https://blog.tehybug.com/index.php/2022/02/20/tehybug-senseair-co2-sensor/

This means that the new board is even more compact and can fit into tight spaces, making it ideal for a wide range of applications.

To showcase the new board in action, we’ve created a 3D printed enclosure and put together a demonstration video, which you can watch here: https://youtu.be/aRd_TyuY4yc. The video demonstrates the board’s features and capabilities, including the OLED display connector.

To make the most of the new board’s features, we’ve also released firmware that includes support for OLED displays and HomeAssistant autodiscovery. This firmware is available on our GitHub repository at: https://github.com/gumslone/tehybug/tree/master/tehybug_co2_firmware. This allows users to easily integrate the new board into their existing smart home setups and access sensor data in real-time.

But that’s not all – we’ve also upgraded our Senseair S8 board to support a display connection, making it even more versatile and useful for a range of applications. This upgrade provides even more options for displaying sensor data and makes the board even more accessible for DIYers and smart home enthusiasts.

At TeHyBug, we’re committed to providing high-quality products that are both reliable and easy to use. With our new mini CO2 sensor board and upgraded Senseair S8 board, we’re excited to offer even more options for monitoring air quality and integrating sensors into smart home setups. For more information about our products and to stay up-to-date on our latest developments, be sure to visit our website and blog.

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.

New TeHyBug device with CO2 Senseair S8 sensor that also supports additional TeHyBug Universal sensors. Unfortunately, the default TeHyBug software is not supported by this new device, it wasn’t developed yet, but you can flash EspHome to it and connect the device to your home assistant, the configuration for EspHome I will post below.

The features:

• SenseAir S8 CO2 Sensor
• ESP8285 Wifi Chip that serves the sensor data directly to homeassistant, no zigbee gateway etc. needed.
• CH340 USB to UART Chip for flashing and programming
• 4 Buttons: 1 Mode (set flashmode), Reset, IO_5 and IO_14 are free programmable
• TeHyBug Universal sensor connector to extend the device with. more sensors, like temperature, humidity, barometric air pressure, UV Light or Luminance
• WS2812B indicator LED, for indicating the Air Quality

TeHyBug 18650 Universal is well suited for the outdoor weather station, it large capacity battery which will last for a long (depending on the data frequency and wifi connectivity) it also has a charging circuit, where you can connect a 5.5V solar cell to charge the battery.

Swappable sensors provide you many possibilities for measuring environmental data. It has a tight-fit pin header connector that can accept VCC->GND->i2c sensor modules like BME680/BME280/BMP280
