ESP32 Renault TPMS sensor RF simulator

Description:

RF signal generator to simulate 433Mhz Renault TPMS sensor. The Simulator uses ESP32 companioned by CC1101 to transmit RF signal.

Hardware:

Components:

• ESP32 Dev kit such as that. - 4$

• CC1101 module such as that. - 2.7$

• Total under 7$

Wiering:

See wiering diagram.

Code:

installation:

Prerequests:

• Arduino IDE.
• ESP32 Board (I use DEV Kit).
• CC1101 Board (I use 8 pins TZT CC1101).
• Install in Arduio IDE the following libraries:
  • ELECHOUSE_CC1101_SRC_DRV
• locate the directory where Arduino IDE stores the projects (for windows usually in Arduino folder under DOCS).
• Download Zip file of the repo using the Green Code pull down on the upper right corner of this page.
• Unzip the foldeer into the Arduino projects folder you located.

Upload:

• Opened Arduino IDE.
• Open the ESP32_TPMS_Sim project.
• Hit the upload button on the upper left corner (right arrow icon).
• If there are any errors follow the messages (most likely it is missing library).
• Depend on the board you use you might need to manually put your board into upload mode (usually holding both push buttons then releasing the reset butteon and only after a second or so the other button).
• When upload is done you might need to reset the board again.
