Microcontroller Projects: Fridge Temperature and Humidity Indicator

We can measure temperature and humidity inside the fridge using a normal temperature-humidity indicator but relative humidity (RH) could be inaccurate in that case. The moment the fridge door is opened, RH will shoot up due to ingress or egress of moisture in the surroundings. The small sniffer device, described in this article, picks up […]

Ultra-Low-Power Sensor Hub Using nRF24L01 Modules

Presented here is an ATmega328P microcontroller-based ultra low power sensor hub using nRF24L01+ radio frequency (RF) transceiver modules having transmitter and receiver units. The transmitter sends humidity and temperature values of a place to the receiver kept at a remote location for display on an OLED module. The nRF24L01+ module used in the receiver unit

Four Channel Temperature Controller 1

Four Channel Temperature Controller

For our final project, we designed a 4-channel temperature controller using PID control. The system was designed to monitor and regulate the temperature of four individual channels by applying 120V to heating elements using on/off switching. This switching was indirectly manipulated by the micro-controller using relays. Data was continuously collected from resistive thermal devices (RTD’s)

Flame Sensor Interfacing with Arduino

Interfacing Flame Sensor with Arduino to Build a Fire Alarm System

In this article we interface Flame Sensor with Arduino and learn all the steps to build Fire Alarm System by using Arduino and flame sensor. Flame sensor module has photodiode to detect the light and op-amp to control the sensitivity. It is used to detect fire and provide HIGH signal upon the detection. Arduino reads the signal and provides alert by
