RF Serial 433Mhz Module HC-12 (1000M)
Getting and sending data from/to your project won't be a hassle as this module could reach up to 1000m (1Km) in open space.
This module has a wireless working frequency of 443.4MHz to 473.0MHz with up to 100 communication channels. It also has a transmitting power of -.79mW(-1dB) with a maximum of 100mW(20dBm), with 3 working modes that adapt to different application situations. It has an operating temperature of -40°C to 85°C.
You could integrate this with your MCU by connecting it to the UART(RX/TX) of your MCU plus the power supply (VCC, GND).
This module is a substitute in projects deployed in the absence of wifi or areas with a low cellular signal.
