Description
The MClimate Wireless Thermostat is a stand-alone device powered entirely by solar energy via an organic solar panel. It features a 2.9-inch e-ink screen, a passive infrared (PIR) motion sensor, temperature and humidity sensors, a LUX sensor, and three physical buttons. Users can adjust the target temperature and view current indoor conditions. The device transmits data periodically and upon detecting events. Information from the Wireless Thermostat can be integrated into any LoRaWAN-compatible system, including Building Management Systems, for controlling various building appliances.

Organic Solar Cell
The device is powered by an organic solar cell. The following graphs illustrate its performance and sensitivity.
Solar Cell Sensitivity
Graph showing the normalized intensity (a.u.) of the organic solar cell's sensitivity across wavelengths from 300nm to 800nm. It is compared against the emission spectra of typical indoor fluorescent lights, a 3000K LED lamp, and a 5000K LED lamp. The organic solar cell shows peak sensitivity in the blue-green light spectrum.
Output Power vs. Illuminance
Graph showing the output power (µW) generated by the organic solar cell relative to illuminance (lux). The measurements were conducted under controlled conditions: temperature of 22°C, humidity of 40% RH, and a warm white LED light source (3500K). The output power increases with higher illuminance.
Installation Warnings
Important Warnings:
- ❌ Do not expose to direct sunlight. This can damage the indoor organic solar cell.
- ❌ Do not install near air vents.
- ❌ Do not install near heat sources (e.g., radiators).
