We will use a module ESP8266 12E NodeMCU and the Onewire library, in this case, step by step the methods of sending and requesting sensor data. In this case we have adapted our temperature sensor for fast connections, the sensor, the datasheet of DS18B20Maxim recommends using a resistance of 4.7k, but we will use a r esistance of 3.3k, but for ease we will use 3 resistors of 10k in parallel, This modification will allow your ESP8266 modules to work with this sensor without difficulty, with the help of heat shrinkable resistors and wiring. There are a variety of sensors to measure temperature in devices such as Arduinoand ESP8266, in this case we have chosen the Sensor DS18B20this particular sensor is not connected through a GPIO Analogue, technically it is a digital sensor that uses the protocol Onewire or 1- Wire designed by dallas semiconductor, There are many tutorials on the net about this protocol.Ī Product – Enterprise DIY Outdoor Gateway LoRaWan Network Gateway Builtin OpenWRT OS with LoRa GPS WIFI LTE Antenna IP67 Waterproof Q123
