Interfacing HDC1000 temperature/humidity sensor to Arduino

HDC1000 is small (8BGA) digital temperature/humidity sensor from TI which can be interfaced through I2C. Despite its small size, few newt features makes it really attractive. For instance sensor on package is located on the bottom so it’s not exposed to dust. Also there is a dedicated DRDYn pin which signals when new reading on chip is ready. This way you can build pretty effective applications where sensor itself can trigger MCU interrupt which could also wake it from sleep only when needed. Obviously for hobby projects 8BGA package may be little too small to work with. So for prototyping some sort of breakout board is needed. Francesco have built breadboard compatible breakout board which have necessary pins, I2C address selection and pull-up resistors ready to use it as compact… Continue reading

Have a Brand New Experience with Weather Canvas!

Mother Nature is always full with many unexpected surprises. That is why some people enjoy the outdoor activities, such as hiking, trekking, kayaking and so on, rather than staying at home in weekend! The only matter is weather is constantly change and unpredictable. Maybe it full with sunshine in the morning, but it rains heavily in the afternoon! It will cause some difficulty, especially for those who planning to have some outdoor activities. In this case, you might need an assistant to help you overcome the matter. Well, Weather Canvas is coming for the rescue! A little bit different from other DIY weather station, Weather Canvas is a outdoor wireless weather monitoring system coupled with an indoor LED display. For your information, the outdoor system consists of a microcontroller, temperature… Continue reading
