Product Information

This is the replaceable remote sensor for the Pro-Leaf BECC-B2 multi-function environmental controller. It reads CO₂, temperature, humidity, and light so the B2 can hold the room where you set it.

For the B2 controller only

Use this sensor with the Pro-Leaf CO₂ Controller — BECC — B2 (PLCO2B2). Do not pair it with the B1 (PPM) controller. B1 and B2 sensors are not interchangeable.

When you need it

Plug-and-play replacement when the original B2 remote sensor is damaged, drifted, or due for swap. Keeps the controller working without replacing the whole unit.
