This project is a small automatic cooling system for home theater rack. It supports 2 temperature sensors for different zones in the rack and 2 12V PWM fans (standard for PC case cooling).
There is a power switch connector for a switch mounted on the casing (will be designed and 3D printed later). A reset button is provided mostly for reprogramming purpose. There are 4 buttons for setting up temp...
PCB is used to control 3 typical CPU fans with mounted high-power LED chips according to temperature and tach sensors
Relays are used to power-off LED drivers in case of fan failure or overtemperature condition
Universal board for Arduino Nano and UNO and Nano shield with NRF24L01 transmitter, 16x02 LCD I2C SPI (PCF8574) display, two KY-040 Rotary Encoder, GY-521 ITG/MPU (MPU6050), Adafruit 9DOF (LSM303DLHC+L3GD20), MH-FMD BUZZER, DHT11 Humidity & Temperature Sensor, BME280 Pressure Humidity Temperature Sensor Module, MQ-8 and MQ-9 GAS SENSOR, With additional areas for dip and soic.
A fully featured board based on ESP8266 and MAX31855 for managing temperature of electric ovens either by on-off or by pid control. The board supports 2 independent temperature probes and 2 relays for 2 independent heaters. All the operations (set temperature, start, stop, status monitoring) are performed by accessing a standard html webpage with a browser (software is found at https://github.com/...

**Description**: This is an evaluation board for the MLX90614 IR Thermometer. The sensor is connected to an ATmega328 running at 3.3V with a STK500 (Arduino) 8MHz bootloader. Code can be loaded through the FTDI basic interface and the Arduino environment.
The MLX9061 sensor is a high precision, small size, single zone IR...
Homely WSN Basic Board V2 is an IoT board to collect environmental data (temperature, humidity, and pressure) and to push them to a centralized server through Wi-Fi. This is the enriched successor of the Basic Board V1, that improves different aspects:
- energy efficiency (lower consumption during deep-sleep)
- onboard recharge for single-cell Lipo battery
- measurement of battery level based on...
More compact speedometer with OLED display and temperature measurement.
This is the version 2 of the ATtiny85 speedometer. It features an ATmega328p uC that has more memory, pin functionalities, higher frequency and to which you can easily find the needed libraries (the ATmega328p is used on Arduino Uno). A serial-to-USB converter is needed for programming. It has the previous version's batte...
Temperature, humidity and luminance sensor based on ESP12-E (ESP8266).
- The temperature and humidity sensor is DHT22, but you can setup any other.
- The pir sensor could be any with abinary digital output.
- The luminance sensor is based on ADC
USB port is only for power (you can also power it by the header male pins).
For programming you have to use the UART pins.
## Arduino drives A single wire digital temperature sensor ##
DS18B20 fromMaxim (formerly Dallas) is a great chip to measure temperature in your project. Fortunately, the Dallas emperature library which makes use of the sensor is easy to Arduino.
In the latest version of the library can be found here

**Description**: The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a tempe...
AxH is an Italian Community of homebrewing passionates.
AxHTherm is a smart device born to help home brewers to take control of their fermentation chambers.
It allows to define temperature steps, temperature ramps, and gravity set points to guide your fermentations!
You don't have to be nearby your fermentation chamber anymore! With AxHTherm you can remotely manage your fermentations, and trac...
