Two devices. Complete coverage.
Every RecessD deployment runs on the same two pieces of field hardware — one that senses, one that controls. Simple to install, engineered to last.
RecessD Sensor
Every condition that matters, detected wirelessly.
Temperature, humidity, and open/closed state, reported wirelessly over LoRaWAN — no wiring, no on-site gateway, no compromise. Two AA batteries power it for up to ten years, so once it’s placed, it’s done. An integrated I2C bus extends what it can see: we’ve already paired it with natural gas and CO2 sensors, and built it to take on whatever comes next.
- Temperature
- Humidity
- Open / closed contact sensing
- Up to 10-year battery life on two AA batteries
- I2C expansion bus for additional sensors
- Deployed today with natural gas and CO2 sensors
RecessD PLC
The controller behind the equipment.
Three relays, two digital inputs, an analog output, and integrated thermistors — unified in a single wireless controller. The RecessD PLC is engineered to interface with HVAC systems, fire systems, and nearly any piece of building equipment, giving every device on the network a single, reliable point of control.
- 3 relays
- Integrated thermistors
- 2 digital inputs
- 1 analog output
- Interfaces with HVAC, fire systems, and general building equipment
What it enables
Built for real building problems.
The same Sensor and PLC, reconfigured, cover the use cases our customers ask for most.
Demand control kitchen ventilation
Kitchen exhaust and makeup air are matched to actual cooking load in real time, not run at full power around the clock — cutting energy use without sacrificing air quality or code compliance.
Leak detection
Continuous monitoring for water intrusion in mechanical rooms, kitchens, and other high-risk areas — an alert reaches your team the moment a leak begins, long before it becomes a repair bill.
Natural gas detection
Dedicated gas sensors, integrated over the same wireless network as every other device, watch continuously for unsafe concentrations and notify staff immediately — a safety layer with nothing separate to install or maintain.
Thermostats with overnight setback
Every thermostat on the network follows a schedule, not a memory. Temperatures pull back automatically after hours and recover before opening, cutting HVAC runtime without anyone touching a dial.
Lighting control synced to sunrise and sunset
RecessD dimmers give every fixture real control over lighting level, not just on and off — brightening, dimming, and switching signage automatically as the solar calendar shifts, within minutes of actual sunrise and sunset, every day, with no manual schedule to maintain.
Presence detection (mmWave radar)
mmWave radar integration senses whether a space is occupied, not just whether a switch was flipped — so lighting, HVAC, and equipment respond to real occupancy, and rooms only run when someone is actually in them.
