Touch@Glass CO₂ sensor
temperature and humidity
1- to 4-module, with custom graphic design and replaceable glass
Touch@Glass CO₂ sensor
The module measures CO₂ concentration, temperature and humidity in the room. Three LEDs on the glass show air quality. Typical use: ventilation control in schools, offices, meeting rooms and bedrooms.
It fits in as one of the switch positions; no separate wall sensor is needed. It is a member of the Touch@Glass family. It combines with either Touch@Glass or Touch@Glass EVO switches.
Air quality indicator on the glass
Three LEDs in the middle of the glass: green at normal quality, amber above 1,000 ppm, red above 1,500 ppm.
CO₂, temperature and humidity in one module
Sensirion SCD4x: 0 to 32,767 ppm CO₂, −10 to +60 °C, 0 to 100 % RH.
Key features
- The Touch@Glass CO₂, temperature and humidity sensor is a wall-mounted device for continuous measurement of CO₂ concentration, temperature and relative humidity. It is typically used for ventilation or HVAC control and indoor air quality monitoring — in combination with a TECO or Modbus control system.
- The sensing element itself is located behind the decorative cover glass; air access is provided by a tunnel in the housing with a vertical passage. Three LED indicators showing CO₂ concentration are positioned in the center of the cover glass — green at normal air quality, orange when concentration exceeds 1,000 ppm, and red when it exceeds 1,500 ppm. The threshold values are fixed in the module firmware for automatic mode; in manual mode the LEDs can be controlled freely.
- The device is suitable for residential buildings, offices, schools and industrial facilities where air quality monitoring is required to maintain a healthy and comfortable indoor environment.
- 2 universal inputs (analog/digital) are available for connecting external sensors or potential-free contacts.
- Design and functions customized to the interior; user-replaceable glass.
- Touch@Glass sensors are part of the TECO control system and communicate via the TECO CIB bus. Both power and communication are provided by a single bus cable.
- Touch@Glass is available in 1-module (94×94 mm), 2‑module (94×165 mm), 3-module (94×236 mm) and 4‑module (94×307 mm) configurations.
- The front panel consists of 4 mm safety tempered glass with custom printing.

Under one glass with other modules
- Can be combined under one glass: the CO₂ module with a Touch@Glass or Touch@Glass EVO switch and with the RFID reader
- Cannot be combined: the CO₂ module with both product lines at once
- Standalone only: fingerprint reader (1 module, 94 × 94 mm)
