What does a water level sensor module do?
This water level sensor module has a series of parallel exposed traces to measure droplets/water volume in order to determine the water level. Very Easy to monitor water level as the output to analog signal is directly proportional to the water level.
How do you interface a soil moisture sensor with NodeMCU?
Connect the two pins of the moisture sensor to the two pins on the Amplifier circuit using jumper wires. Connect the Vcc from the Amplifier to the 3.3V pin on the NodeMCU. Connect the GND pin to the ground (GND) pin on the NodeMCU. Connect the Analog pin to the A0 pin on the NodeMCU.
How does a washing machine water level sensor work?
Water Level Switch Function The water level switch sends power from the timer control to the water inlet valve and the temperature switch each time the tub needs to be filled during a wash cycle. The switch then signals the motor to begin agitating.
Which sensor is used in water level indicator?
magnetic float sensor
A magnetic float sensor is a device used to detect the level of liquid within a tank. The switch may be used in a pump, an indicator, an alarm, or other devices. Magnetic float sensor is an electromagnetic ON/OFF switch. It helps to sense the level of water present in the overhead tank or sump.
How do you send sensor data to ThingSpeak using ESP8266?
ESP8266 IOT Using Arduino and ThingSpeak
- Step 1: Materials You Need. You will need:
- Step 2: Setup. Connect SFE Duino and ESP-8266 Wirelss Module with jumper wires as schematic above.
- Step 3: Connect With ThingSpeak.
- Step 4: Code.
- Step 5: Monitor It!

How many sensors we can connect to Nodemcu?
The disadvantage of using Nodemcu alone is that, you can monitor only one analog sensor, as in Nodemcu ESP8266 Wifi Module we have only one analog pin A0. We can use Nodemcu esp8266 wifi module with the Arduino Uno or Mega and connect as many sensors as we want.
How to use NodeMCU for water control and monitor?
1. NodeMCU ESP-12E 2. Liquid Level Sensor (calibrate first to get top level value and bottom level) If you need more deep sensor, you can cut the top strip of sensor and take some wire to two side of sensor 6. Jumper Cable 1. Arduino IDE
Can a float sensor be used to monitor water level?
Here we are building an IoT water level monitoring system using a float level sensor and NodeMCU ESP8266 to monitor the level of water and publish it on a web-server. This system will turn on the water pump automatically if the water level goes low and turn off the water pump when the water level reaches to full capacity.
How to control water level with NodeMCU and Cayenne?
Add Valve Switch widget from Cayenne Dashboard, and select Virtual Pin 1. Add Analog Sensor widget from Cayenne Dashboard, and name it to Water Level, select Virtual Pin 10, Unit Percentage Add triggers and set if water level above 100 % then valve switch turn off. Add triggers and set if water level below 100% then valve switch turn on.
When to close water valve in NodeMCU project?
The valve will close when water reached top level of the sensor. This project is to ensure that water reservoir always in full condition, because in my location the water supply only flow when midnight, but if midnight we are not need water. 1. NodeMCU ESP-12E 2.
