ideas become reality
With thoughts to miniaturization, the NDIR (Nondispersive Infrared Sensor) technology seems to reach a limit for CO2 sensors, as the sensor sensitivity is directly equivalent to the optical beam path length and thus the sensor size. The Sensirion is always
The SGP30 is a digital multipixel gas sensor designed for easy integration. The SGP30 is a complete sensor on a single chip an integrated i2c data interface with a temperature controlled micro hotplate and two preprocessed indoor air quality signal
The basic principle of metal oxide sensors is the resistance of detection layer changes at the presence of the targeted gasses. Oxidizing gases such as ozone or nitrogen di-oxide the resistance will increase and gases such as carbon monoxide the
This is the SFM3000 a Mass Flow Meter develop by SENSIRION. This can measure a bidirectional flow of air and other non-aggressive gases at rate up to 200slm superb accuracy and extremely high speed output at 14 bit/ 2kHz rate.
This the MAX30105 an integrated particle sensor. This device includes internal LEDs, Photodetectors, Optical Elements, with advance low noise electronics and light blocking. This provides a complete system on chip solution to ease the design process of a smoke detection
This the Telaire T6713 / T67XX a Carbon Dioxide CO2 sensor for indoor air quality, energy saving application, control of ventilation, environmental purpose, farming, and clinical instrumentation. The T67XX is already factory calibrated sensor than can measure the concentration level
Another project that demonstrate how to build a low cost lake/pond water level logger sensor that can be deployed without an RF communication. however this project works as independent/standalone can be deployed on a remote area intended for science and
This is a steam sensor which is can sense a rain drops, steam or water vapor suitable of IOT project. The illustration below use LM3XX as differential comparators that drives the difference between the two inputs. The LM3XX device is
