Working smoke detectors can often mean the difference between life and death. However, maintaining these detectors can be difficult because they rely on finite power sources that need to be monitored and changed frequently, leading to high resource and staffing costs. Zepsor has developed a solution to these power and maintenance concerns at the source. Their novel sensing technology operates passively until the presence of a flame is detected. By repurposing the energy of the flame itself, the sensor can turn “on” and transmit a signal, thereby preserving precious battery power until it is absolutely needed. As a result, Zepsor’s smoke detectors can last many times longer than existing models, reducing costs while simultaneously providing a consistently safer environment.
