Heiman WS-720ES Tuya WiFi Smart Carbon Monoxide Detector Heiman WS-720ES Tuya smart WiFi carbon monoxide sensor The Heiman WS-720ES sensor is a device that provides protection against harmful concentrations of carbon monoxide in the air. Equipped with modern electrochemical technology, it offers high precision detection and reliable operation. Thanks to WiFi communication, you receive instant notifications of detected danger to your mobile device. Electrochemical technology The Heiman WS-720ES sensor uses advanced electrochemical technology to detect carbon monoxide. It provides superior accuracy and speed of response to changes in CO concentration in the air, allowing you to be alerted quickly and effectively to a potential threat. Digital temperature compensation The device is equipped with digital temperature compensation technology, which minimizes the impact of environmental conditions on measurement accuracy. As a result, the sensor maintains high detection accuracy over a wide temperature range, from -10°C to +40°C. Low energy warning The carbon monoxide sensor is equipped with a low-energy warning function that alerts you when the battery needs to be replaced. This provides continuous protection and confidence that the device will work properly at all times. Hush mode The device also has a Hush mode, which allows you to temporarily silence unwanted alarms for 10 minutes. This is particularly useful in situations where an alarm is triggered accidentally and the threat is not real. In addition, this mode can silence an alarm for 12 hours in the event of low voltage or a fault. Real-time monitoring The Heiman WS-720ES sensor transmits information about detected carbon monoxide in real time to the Tuya (Smart Life) mobile app. The user receives instant notifications of the threat, allowing them to react quickly and take appropriate action to ensure the safety of the household. Stylish design The sensor features a modern and elegant design that blends harmoniously into the decor of any interior. Its compact design allows it to be mounted discreetly on the wall or ceiling without disturbing the aesthetics of the room. Included
