Iluminar HASH Environment Sensor Module | PAR Temp RH CO2 VPD

Iluminar HASH Environment Sensor Module for Wireless Room Monitoring

The Iluminar HASH Environment Sensor Module is a wireless multi-zone probe. It pairs to the HASH Lighting Controller and feeds it real-time PAR, temperature, humidity, CO2, and calculated VPD. Inside the housing: a Bosch BME280 for temp and RH, an industrial-grade SH-DS NDIR CO2 sensor, and a phototransistor for light. Connection back to the controller is RF wireless. Up to 1100 m line of sight, with practical 50-100 m in a built-out facility.

Why Multi-Zone Wireless Sensing Beats a Single Wired Probe

A wired 4-in-1 ties the controller to one location. The HASH approach lets up to six wireless sensor modules run off a single HASH controller. A flower room, a veg room, and a drying space each get their own probe — and the controller logs all three independently. Growers typically place the modules at canopy height in the center of each zone. CO2 needs about a 90-second warmup before readings stabilize. iOS and Android apps drive setup; no PC required.
