Wiring the MAX30150 Particle / Smoke Detection Sensor

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

Wiring the TELAIRE T6713 / T67XX a Carbon Dioxide CO2 sensor

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

Water/Liquid Level Data Logging on microSD and RTC

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

Wiring SenseAir LP8/S8 IR CO2 Sensor on TI CC3200 IOT-MCU

SenseAir Miniature (Carbon Dioxide) CO2 Sensor are non-dispersive small package infrared (NDIR) sensor, a new optical design that enable a precise and accurately measures carbon dioxide level up to 5% that runs on 30mA design for long-term battery or solar

Wiring 2N7000 AN10441 as Logic Level Converter for i2C Protocol Devices

Other micro-controller uses 5v as standard input voltage, many latest device modules, popular sensors, GPS, RF modules, Flash Memories, SPI storage, Display, use 3 to 3.3v  most of this devices requires logic level conversion to protect them from high voltage

Wiring the ORP Oxidation-reduction Potential Sensor with pH/ORP Probe on ESP / Arduino Microcontroller

This is ORP OXIDATION-REDUCTION POTENTIAL probe sensor, Oxidation is the loss of pf electrons and reductions and gain electrons. The probe are represented in millivolts can be positive or negative, the same like pH that measures hydrogen ION activity in
