NodeMCU ESP8266 CP2102 NodeMCU WIFI Serial Wireless Module

  • ESP8266 CP2102 NodeMCU LUA ESP-12E WIFI Serial Wireless Module
  • Built-in Micro-USB, with flash and reset switches, easy to program
  • Full I/O port and Wireless 802.11 supported, direct download no need to reset
  • Arduino compatible works great with the latest Arduino IDE/Mongoose IoT/Micro python

  • Operating Voltage: 2.5V to 3.6V
  • On-board 3.3V 600mA regulator
  • 80mA Operating Current
  • 20 µA during Sleep Mode


The ESP8266 requires a 3.3V power supply and 3.3V logic levels for communication. The GPIO pins are not 5V-tolerant! If you want to interface the board with 5V (or higher) components, you’ll need to do some level shifting.

DHT11 Module

  • Operating Voltage: 3.5V to 5.5V
  • Operating current: 0.3mA (measuring) 60uA (standby)
  • Output: Serial data
  • Temperature Range: 0°C to 50°C
  • Humidity Range: 20% to 90%
  • Resolution: Temperature and Humidity both are 16-bit
  • Accuracy: ±1°C and ±1%



Power supply 3.5V to 5.5V



Outputs both Temperature and Humidity through serial Data



Connected to the ground of the circuit

Tilt Switch Sensor

A Tilt Sensor switch is an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a mercury ball inside it that moves and makes the circuit. So the tilt sensor can turn on or off the circuit based on the orientation.

The tilt sensor is cylindrical and contains a free conductive rolling ball inside with two conductive elements (poles) beneath.

Here’s how it works:

  • When the sensor is completely upright, the ball falls to the bottom of the sensor and connects the poles, allowing the current to flow.
  • When the sensor is tilted, the ball doesn’t touch the poles, the circuit is open, and the current doesn’t flow.


Pin No:

Pin Name:




This pin powers the module, typically the operating voltage is +5V



Used to connect the module to system ground


Digital Out

You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer


Analog Out

This pin outputs 0-5V analog voltage based on the intensity of the gas

  • Operating Voltage is +5V
  • can be used to Measure or detect LPG, Alcohol, Propane, Hydrogen, CO and even methane
  • Analog output voltage: 0V to 5V
  • Digital Output Voltage: 0V or 5V (TTL Logic)
  • Preheat duration 20 seconds
  • Can be used as a Digital or analog sensor
  • The Sensitivity of Digital pin can be varied using the potentiometer


The specifications of the soil moisture sensor FC-28 are as follows

Input Voltage

3.3 – 5V

Output Voltage

0 – 4.2V

Input Current


Output Signal

Both Analog and Digital

The soil Moisture sensor FC-28 has four pins

  • VCC: For power
  • A0: Analog output
  • D0: Digital output
  • GND: Ground

The Module also contains a potentiometer that will set the threshold value and then this threshold value will be compared by the LM393 comparator. The output LED will light up and down according to this threshold value.


The Light Dependent Resistor (LDR) is just another special type of Resistor and hence has no polarity

  • Operating Voltage: 3.3V to 5V DC
  • Operating Current: 15ma
  • output Digital - 0V to 5V, Adjustable trigger level from preset
  • Output Analog - 0V to 5V based on light falling on the LDR

Pin details

  • VCC = 3.3V to 5V DC
  • GND = Ground
  • S = Output
