IoT Energy Harvester using Cayenne
For decades, people have searched for ways to store ambient energy, and in the age of Internet of Things devices, this is combined with the desire to power sensors and mobile devices. This project demonstrates a basic eco-friendly implementation of a solar powered IoT sensor.
On a high level, The IoT Solar Harvester transmits sensor data using a WiFi connection. It is powered by solar energy, which is gathered and managed by an energy harvester (LTC3106) that powers the IoT sensor and stores excess energy into a rechargeable battery, to be used when the solar panel doesn’t provide enough power.
The IoT Sensor is connected to a Sparkfun ESP8266 Thing – Dev Board which manages the Continue reading
Smart Modular Watering System using Blynk
In a fast growing world of things connected to the Internet, you will find a lot of projects focused on
making us lazy automation. Well, this is no exception!. The Smart Modular Watering System uses the SparkFun Blynk Board – ESP8266 with the Blynk app to connect to the Internet of Things.
Its main purposes are to water the plants automatically at the right moment and to monitor the level of the water reservoir. It also let users monitor some useful data using the Blynk app like the UV index, current soil moisture, temperature and humidity.
The Blynk app also allow users to change some parameters, like the watering interval, watering duration, some thresholds and Continue reading
