ONiO, a Norwegian healthcare-focused Internet of Things (IoT) expert has unveiled ONiO.zero, an ultra-low-power RISC-V-based microcontroller capable of operating solely from harvested energy — without needing a battery, capacitor, or any other means of energy storage. The company says “ONiO.zero is an ultra-low-power wireless MCU that uses energy harvesting technology.” This indicates that the ONiO.zero solely functions on energy harnessed from its surroundings. With

With this device you diminish the use of water in your house or work. Instead of waiting to see vapor in the shower to get in, this device help you to know when the water its at the temperature you want and you can instantly enter to the shower. In this way you don’t waste the water
Temperature Sensor for Shower using Arduino Continue Reading
TE Connectivity released the HTU31 humidity and temperature sensor, presented as one of the smallest and most accurate humidity sensors currently available. The sensor provides precision measurement, fast response time, low hysteresis, and sustained performance, even in harsh environments. The HTU31 keeps a strict linear response curve through its humidity (0-100%) and temperature (-40° to 125°C) ranges, respectively, and
