· The LM35 temperature sensor is a three pin device (VCC, OUT and GND) with an output voltage linearly related to Centigrade temperature. Since the LM35 output varies with dependent to the temperature, we need an ADC (Analog-to-Digital Converter) module to measure this voltage. The NodeMCU microcontroller (ESP8266EX) has one ADC module with 10-bit resolution. The LM35 …
· For sending the measured TDS, EC & Temperature data, we need an IoT platform. The best free IoT platform is Blynk. The ESP8266 based TDS Meter connects to wifi and continuously sends the data to the Blynk application. Thus you can get a 24×7 report related to your water quality. Thus TDS sensor is the best sensor for Water Quality Monitoring.

· IoT Weather Station using NodeMCU: Monitoring Humidity, Temperature and Pressure over Internet; Raspberry Pi Weather Station: Monitoring Humidity, Temperature and Pressure over Internet But here, for a thermal gun we need a sensor that could sense the temperature of a particular object (not ambient) without directly getting in contact with the object. For this purpose we have …
Connecting IR sensors to a NodeMCU is really simple. The IR acts as a digital output so all you need to do is operate the pin to flip high (detected) or low (not detected). Check out the images for more details. Power is usually 3-5v DC input. Every IR modules have a 3-pin connection.. The circuit connections are made as follows:. Vcc pin of the IR module is connected to +3v of the NodeMCU.
· The DS18B20 temperature sensor is a 1-wire digital temperature sensor. Each sensor has a unique 64-bit serial number, which means you can use many sensors on the same data bus (this means many sensors connected to the same GPIO). This is specially useful for data logging and temperature control projects. The DS18B20 is a great sensor because it is cheap, accurate and very …
· In this Project we will explain how to remote control air conditioners ( turing it on\off, set temperature or fan speed).
