The Microclimate Reality

Your Climate Computer is Blind

Most climate computers rely on a single measuring box hanging in an empty walkway. But plants create their own microclimate. Without a leaf sensor at canopy level, you are relying on aisle data, which leads to:

Relying on aisle data leads to:

Hidden Humidity

Pockets of wet air that trigger Botrytis.

False Security

Thinking the VPD is safe when the plant is actually stressed.

Lab Precision. Zero Cables.

Professional-grade leaf monitoring — ±0.3 °C accuracy, every 5 minutes — without the infrastructure complexity

Ventilated Shield

Active airflow ensures the sensor measures the true microclimate the canopy experiences, not just stagnant heat.

Ventilated radiation shield – accurate greenhouse air temperature measurement

IR Plant Sensor

The infrared leaf temperature sensor reads the canopy directly — no contact, no wires — to calculate the real VPD.

Infrared plant sensor – non-contact canopy temperature measurement in greenhouse

Solar Engine

Self-charging and always on. Install it anywhere in minutes.

Solar-powered engine – Pixel sensor runs autonomously without cables in greenhouse

No Cables. No Electrician. No Delays.

Deploy your leaf sensor in minutes, not days. Pixel’s solar power and wireless connectivity mean zero installation complexity.

Master the Dew Point.

Fungus thrives when leaf temperature hits the dew point. Continuous leaf monitoring alerts you before
condensation forms, so you can heat or vent proactively.

Frequently Asked Questions

Both. Pixel is a canopy sensor that measures leaf temperature, air temperature, humidity, dew point, and leaf-level VPD — all from one solar-powered unit mounted in the crop. Most greenhouse sensors sit in the aisle and read the air. Pixel reads what the plant actually experiences.

A climate computer measuring box hangs in the walkway and reads aisle conditions. Pixel sits inside the crop canopy with an infrared leaf temperature sensor, so it picks up the microclimate your plants actually live in — including hidden humidity pockets, dew point risk, and real VPD at the leaf.

No. Pixel is fully solar-powered and connects over LoRa wireless with a range of 300–500 m. You place it in the crop, and it starts sending data within minutes. No cables, no electrician, no delays.

Yes. Pixel integrates directly with Priva, Hoogendoorn, and Ridder via API. The data feeds into your existing system — no rip-and-replace.

That depends on your crop and layout. Most growers start with a grid to map climate uniformity — hot zones, cold zones, humidity pockets. Sigrow will recommend the right number of sensors for your setup after a short consultation.
