Measuring & Control — AC Infinity

This page holds the part of AC Infinity that drives everything else. Where other brands in this category sell a controller or a meter, AC Infinity sells a system in which the controller, the sensors and their own devices talk to each other. That works well as long as you stay inside the system, and it is why this page is full of cables.

Two controllers

The Controller AI+ and the Controller 69 Pro are the two brains. Onto them go the sensors: a climate sensor for temperature and humidity, a soil sensor, and a CO2 and light sensor. Which sensor belongs to which controller varies, so check that on the product page rather than assuming it.

UIS is the wiring, and it is not always included

Most of this page is UIS parts: extension cables, an angled extension, type A, B and D adapters, a splitter hub and a wireless link. This is the bit people skip when ordering and where the setup then stalls. If your controller hangs a metre from your fan, or you want three devices on one port, you need something from here. Count the distances and the number of devices before you order.

The standalone meters too

Alongside the system, AC Infinity make separate instruments: the Smart Hygrometer B1 and B2, one with an external and one with an internal sensor, plus a digital pH meter kit, a pH Meter PRO kit, a Hydroponic Meter PRO kit and a dual-lens pocket microscope. These work on their own and need no controller.

Frequently asked questions

Do I need a controller to use an AC Infinity fan?
Not always. Check what the fan's own product page says is included before buying a controller separately.

Which adapter do I need?
It depends on the device you are connecting. Types A, B and D are not interchangeable, so check per device.

Where are this brand's fans and tents?
Under Climate and Ventilation, Grow Tents and Lighting, each on its own page.
