ESP8266 client-server based wireless weather station

If you ever tried to build weather station, you probably know that wired solution sucks. For something more serious always go with wireless – this way you are not limited by distance and setup looks clean. Rui Santos have been working on wireless weather station where he implements server-client solution with two ESP8266 modules. Client module takes care of reading temperature from DS18B20 sensor and reads ADC value on one pin. Server side module receives data and transfers to PC using serial interface using FTDI adapter. He used Things Gateway – software written by Roberto Valgolio. It allows reading and writing data from/to microcontroller using excel, csv, send emails and display charts. All you need is to configure Things Gateway to accepts serial data and point it to excel spreadsheet… Continue reading

Wireless Weather Station Equipped with Voice Synthesis

Weather is considering as one of the most unpredictable natural phenomenon on the Earth. Go figure, with all the sudden tornadoes, cyclones, floods, bushfire, and even dust storm violating all across the world, it’s becoming harder and harder to predict the constantly changes of weather! However, there are many people out there have huge interested in the meteorology. If you’re one of the meteorology fans, then you have to hang out here, as we’re about to develop a Wireless Weather Station with Voice Synthesis. Well, the main objective of the project is to create a cheap and maintenance free weather station, which is allowing the paraglider pilots to tell them the current wind condition at their flying site. Unlike the ordinary weather station, this one had access to a PSTN… Continue reading
