Product overview
Description
An Arduino board coupled to this shield allows to measure the percentage of oxygen contained in the smoke or air, calculate the lambda and AFR( air-fuel ratio of combustion).
All features
- Lambda probe interface BOSCH IC CJ125
- Compatibility with wideband lambda probe BOSCH lsu 4.9
- Compatibilities with arduino boards
- Arduino UNO.(stackable)
- Arduino UNO WIFI.(stackable)
- Arduino MEGA.(stackable, need 3 external wires)
Software available for arduino:
- PLSE_1.0.ino: Basic operation to get started. Sends serial data to the arduino IDE.
- PLSE_2.0.ino: Finite state machine controlled wideband lambda probe operating phases. Sends serial data to the arduino IDE
- PLSE_3.0.ino: (HM10 bluetooth module required). Operation controlled by the Smartphone application, communicating via Bluetooth. This application allows you to turn on and off the heating of the wideband lambda sensor and display the data on the smartphone screen.
- PLSE_4.0.ino: Phases of operation of the broadband lambda probe controlled by finite state machine. Sends data to the 1602 LCD display via I2C.
Smartphone App(HM10 bluetooth module required).
Switches the lambda sensor, displays battery voltage, oxygen percentage, lambda and AFR (air-fuel ratio) for different fuels on the smartphone screen. Is available for the following smartphone platforms:
- Android
- IOS(not currently available, available soon)

Tech manual and annex. Controlduino 01S00V00.
230 V AC mains power. Not needed if you run it from a vehicle’s 12 V DC supply.
M18 x 1.5 weld-in bung for the lambda sensor, with optional blanking plug. Only needed if the exhaust or flue has no threaded port. Add the plug only if the sensor will be removed and the port has to be closed.
