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. Key Features Measurements: PAR, temperature, humidity, atmospheric pressure, CO2 PPM, calculated VPD Sensor stack: Bosch BME280 (temp/RH/pressure), SH-DS NDIR CO2, phototransistor light sensor Wireless range: Up to 1100 m line of sight, 50-100 m typical inside a dense facility Multi-zone: Up to 6 sensor modules per HASH controller for separate flower / veg / drying zones App control: iOS and Android — controller setup and zone monitoring without a PC Technical Specifications Specification Value Measurements PAR, temp, RH, atmospheric pressure, CO2 (PPM), calculated VPD Sensor Components Bosch BME280 (temp/RH/pressure), SH-DS NDIR CO2 sensor, phototransistor Wireless Range Up to 1100 m line of sight; 50-100 m typical indoors CO2 Warmup ~90 seconds for stable readings Operating Range 0-65 C (32-149 F) Connectivity RF wireless to HASH Lighting Controller; iOS / Android app Multi-Sensor Support Up to 6 wireless sensor modules per HASH controller
