Hc12 With Arduino Uno

Arduino Code for HC-12 transmitter Version 2.2 Project is create a weather monitoring station, powered by a solar panel which also charges 4 AA batteries. Using a power saving mode never tried, Arduino should run 247. Tried averaging readings, did not work as desired. Sleep mode works if at top of code.

The 433MHZ HC-12 SI4463 Wireless Serial Port Module pins are connected to the Arduino Uno board as follows Pin 9600 Serial port to computer HC12.begin9600 Serial port to HC12 void loop while HC12.available When data is received Serial.writeHC12.read Send the data to Serial monitor while

Arduino UNO-Based Smart Irrigation System with Motion Detection and Bluetooth Connectivity. This circuit is a microcontroller-based control and monitoring system. It uses an Arduino UNO to read from a DHT22 temperature and humidity sensor and an HC-SR501 motion sensor, display data on an LCD, and control a water pump and an LED through a relay

The HC12 is a wireless unit capable of transmitting data over a 12 kilometer away using AT commands and ridiculously simple code. Better than the NRF24L01, we will send a text from one arduino to another. Required Items HC12x2 Antenna Attachmentx1 Diodex2 100FCapacitorx2 Fritzing Sketch Transceiver Assembly

How the code works So once we type something in the serial monitor and click the Send button, at the first Arduino, the while loop with the Serial.available function will become true and using the HC12.write function we will send the data from the serial monitor to the HC-12 module. This module will transfer the data wirelessly to the second HC-12 module, so at the second Arduino the

Arduino UNO x2 USB A Male Cables HC-12 modules x2 Principle of operation. The HC-12 module is a radio frequency module that transmits on the 433.4-470MHzz frequency range. It consists of a radio transceiver Si4463 which manages the wireless communication and a microcontroller STM8S003F3 which manages the serial communication with the

The Arduino Uno will be the base that will perform the reading of two buttons and when the button B0 is pressed, a command will be sent to light the red led and when the button B1 is pressed the blue led will be lit. HC12 Circuit with Arduino UNO. In Arduino Uno, we will have the B0 button connected to digital pin 2 of Arduino Uno and the

Connect the HC-12 as shown in the image and connect the Arduino to your computer. Copy and paste the contents of the file named quotHC-12 AT Commander.txtquot from the ZIP archive and upload to your Arduino. Open the serial monitor and type quotATquot. If the module returns quotOKquot, the command mode is working. Changing the baud rate. Type quotAT
