Flowmeter NodeMcu Counting Litres: This work aims to build an Internet based system that enables the remote monitoring of a water/flow meters.Motivation: In a house or building it is very important to regularly analyze the consumption of water and thus take action, avoiding unneces... Jan 05, 2019 · DHT11 Humidity & Temperature Sensor: The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). In this illustration we will going to wire the ESP8266 12E nodeMCU with Ultrasonic Raging Sensor HCSR04. As you can see the illustration below the sensor trigger pin is connected to D1 which is pin 5 in Arduino Board, and the ECHO is connected to D2 which is pin 4 in Arduino Board.
2020 uog hecas listShuf command in linuxJun 27, 2018 · The ESP8266 module has the deep sleep mode which allows to put it in hibernation to save the battery. You can wake up the module at regular intervals to make measurements and publish them on a server. The RESET pin (RST) is also used to wake the ESP8266. For example, the rising edge (the signal) of a motion detector (PIR) can be used. Jan 26, 2019 · I want to do a project about home water monitoring by using water flow sensor and NodeMCU as a controller. I have a basic code of count the water usage that i copied from esp8266 forum. But the coding only show the output value. I want to add some code: 1) If reach 30 day or every month, the output value turn back to zero. Jul 04, 2019 · In this Project “Nodemcu ESP8266 DS18b20 Waterproof Temperature Sensor Monitoring using Blynk”, you will learn how to use the ds18b20 waterproof temperature sensor with the Nodemcu esp8266 wifi module and display the temperature on Gauges using the Blynk Application. This is an IOT “Internet of things” based project.
Use caution with the length of the wires to your sensors. This water sensor works best with shorter wires between the sensor and the NodeMCU (ESP8266). I installed the sensor with double sided tape (VHB by 3M) with the sensor wires facing down inside a pan with the connector at the top for my water heater. The wires to the ESP8266 board were kept under 6" and the NODEMCU was also double side tape attached to the side of my water heater.
