This is a small (17.9 mm x 10.3 mm) breakout board with Bosch’s BME280 pressure, temperature, and humidity sensor as well as AMS’ CCS811 digital gas sensor. The sensors work in concert to provide a complete measurement via I2C register reads of indoor air quality including temperature- and humidity-compensated estimates of equivalent CO2 concentration in parts per million (400 – 8192 ppm) and volatile organic chemical concentration in parts per billion (0 – 1187 ppb).

Temperature Controlled Fan With LED Status

This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined threshold.

Simple ATtiny85 fan controller to turn a fan on/off based on temperature. Includes an LED as a temperature indicator. LED is dim at start of fan on temperature and blinks when above a max temperature. Fan is not PWM controlled since I am using a small 5V fan which is quiet running at 100%. The controller is in sleep state while the temperature is below the minimum threshold and wakes up every ~8 seconds to recheck the temperature. When temperature is above minimum threshold, the controller will stay awake checking every second till the temperature falls below the minimum threshold. The code uses ds18b20 library by Davide Gironi.

Make an Arduino Temperature Sensor (Thermistor Tutorial)

In this video, Circuit Basics walks us through the steps in setting up a thermistor temperature sensor on an Arduino Uno. First they show how to output the temperature readings to your serial monitor. Then they go over how to connect and output the temperature readings to a 16×2 LCD display.

Designing a simple and cheap temperature logger

I started with making the TMP102 temperature sensor work. Nothing to say in particular, it’s just an other I2C-small-package-sensor. Or rather SMBus, but apart from the minimum speed clock requirements on the SMBus, the two protocols are alike.

How to Set Up the DHT11 Humidity Sensor on an Arduino

circuitbasics.com has a new tutorial on how to interface DHT11 humidity sensor to Arduino board. Sample code is provided

Because of their low cost and small size, DHT11 humidity and temperature sensors are perfect for lots of different DIY electronics projects. Some projects where the DHT11 would be useful include remote weather stations, home environment control systems, and agricultural/garden monitoring systems.

Intel(r) Quark(tm) micrcontroller D2000 based Environmental sensors board

Sergey Kiselev designed and built an Intel Quark D2000 micrcontroller based Environmental sensors board:

This is a fairly small (51 x 51 mm) board, equipped with a low power Intel Quark D2000 microcontroller, and several sensors (accelerator, temperature, humidity, atmospheric pressure), as well as a mikroBUS compatible header and a Grove compatible connectors, that can be used to connect additional sensors, memory, or radio modules. The board can be used to monitor the environment conditions, and store or transmit the data to a remote system for further processing.

Temperature alarm for boiling milk

image2

Domen Ipavec shares his temperature alarm for boiling milk. Temperature alarm uses an Atmel attiny841 microcontroller, DS18B20 high temperature waterproof temperature sensor from adafruit, 2×16 HD44780 LCD and a buzzer to do its job.

Anyone who has ever boiled milk on the stove knows, that it has a nasty habit of overflowing. That is why I created the temperature alarm for boiling milk to be used my mother. It continuously measures the temperature of the milk and sounds an alarm when the temperature is over the preset alarm value.

CHIP Computer Project: CPU Temperature Monitor with OLED display SSD1306

Today educ8s.tv is going to connect an OLED display to the CHIP 9$ computer in order to monitor its CPU temperature in real time.

I received the CHIP single board computer about a year ago. It is an impressive board, it costs $9 and it offers a 1GHz CPU, 256MB of RAM wifi Bluetooth and many more things. You can watch my review of the CHIP computer by clicking on the card here. As you can see the CHIP computer is a lot smaller than the Raspberry Pi 3 board and of course it costs a lot less. One year later, the software developed for the CHIP computer is mature and we can easily build some projects with it
