Description: Build your own high-precision indoor air quality monitor! This project uses the industry-standard Sensirion SCD41 sensor paired with an ESP32 to track CO2 levels, temperature, and humidity. It is fully integrated with Home…
how to build All sensors are from Sensirion. They all use I²C bus. The two little ones can withstand 3.3V and 5V, the PM sensor needs 5V. I choose to operate the little ones at 3.3V to minimize their heating. The SCL and SDA wires can be…
Simple case for the SCD41 sensor. My specific came from Aliexpress and seems to be a Adafruit clone.
This is a simple case for the SCD41 sensor breakout form Pimoroni. Only the top of the sensor is exposed which minimizes the dead volume and therefore ensures quick sensor response. The shield in front of the sensor protects it from…
Closable case for SCD41 LaskaKit CO2 Sensor. Ready for uSup connection.
Tisk 2 částí. V modelu jsou připraveny oblasti pro větrací mřížku. Stačí nastavit 0 perimetrů a nechat vyslicovat jen výplň. Použil jsem výplň gyroid. Použity šroubky do plastu 2,2x8 mm.
