?Reliable Support?We have prepared detailed weather station tutorial, includes: guidance manual, demo code, burning tools, necessary class libraries. You can contact us on , we will send PDF Document to you. ?Upgrade Accessories? The kit has a wealth of accessories and is a one-stop solution for the IoT weather station! 2 Packs jumper wire: 1 x 10cm 40pin Male to Male / 1 x Male to Female jumper wire. The size is just right for the combined all the modules in the package. ?ESP8266?It can be used in various IoT applications. High performance ESP8266 microcontroller (ESP-12E) with 802.11 b / g / n WLAN and integrated 25dBm antenna. It offers a complete and self-contained Wi-Fi networking solution. The chip is the original chip and can be used directly without additional drivers. It has powerful on-board processing and storage capabilities and perfect match with the BME280 temperature and humidity sensor. ?Larger display?The 1.3" IIC OLED display has a wider viewing range than a 0.96" display. It has low power consumption, fast response and has high resolution (128*64). The bigger the display, the better the display!. ?GY-BME280?Are you looking for a small, precise and energy-saving sensor for temperature, humidity and air pressure to implement your weather station project? Then you are exactly right here! With an I2C connection, it not only reliably displays temperature, pressure and humidity, but also makes some real-time forecasts for your region.
