Pulse Zero Smart Grow Room Sensor | VPD + Temp + Humidity + Lux + Dew Point | Wi-Fi Monitor with Alerts | iOS/Android/PC/Mac

Meet Pulse Zero — a compact, affordable redesign of the hugely popular Pulse One, built on the same proven connectivity platform and internal components. It’s a smart grow room monitor that helps you track, understand, and optimise your environment with live readings, historical charts, and instant alerts if something drifts out of range.

With 24/7 monitoring of the essentials—VPD, temperature, relative humidity, light intensity (lux), and dew point—Pulse Zero makes it easier to dial in consistent conditions for healthier, more predictable results. If your Wi-Fi drops, it includes integrated memory to store data and sync it once you’re back online.

Use it across a single tent or scale it up across multiple rooms: the app supports an unlimited number of sensors, locations, and Wi-Fi networks on one dashboard. You’ll also get day/night averages, custom alert thresholds, and notifications for connectivity or power issues—so you can relax knowing you’ll hear about problems fast.

Designed and manufactured in the USA and built with Swiss-made sensors, Pulse Zero is made for growers who care about accuracy and reliability.
