This semiconductor gas sensor detects the presence of alcohol gas at concentrations from 0.04 mg/L to 4 mg/L, a range suitable for making a breathalyser. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
This is the T5403 breakout board, a fully calibrated barometric pressure sensor with an I2C interface. The T5403 sensor measures the absolute pressure of the air around. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the weather, measure altitude, or any other tasks that require an accurate pressure reading.
This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 10,000 ppm. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
The MCP9701A is an analog temperature sensor which has a measurement range of 0 to +70 Degree C.
