MLX90614 - config

Projects Networking, Protocols, and Devices

Hello

I've bought a MLX90614 temperature sensor.
It seems to be configured in PWM mode by default (duty ratio changes when temperature changes), I want however to use the I2C protocol.

The datasheet specifies which sequence the SCL, SDA pins should receive to switch from PWM to SMBUS (see attached sequence). It's however not clear to me how this can be done with an arduino, can somebody point me in the direction if this can be done with any of the default libraries?

thank in advance

Pull SCL low for 2ms, it seems as easy as that. If you need more help tell us more about your setup (what type of Arduino, wiring diagram, sketch code you use, etc.).
