The Heiman HS1HT Zigbee sensor monitors temperature and humidity levels in your home or office. Easy to install with 3M tape, it connects to smart outlets, air conditioners, or fans for automatic adjustments. Enjoy real-time alerts on your smartphone and create a comfortable, healthy environment for you and your family.

The Heiman HM-5HW is a wireless interlinked heat detector that warns of sudden temperature rises with a loud 85 dB alarm audible up to about 3 metres. It monitors ambient temperature across a wide range (−10°C to +50°C) and triggers when temperatures rapidly climb into the 54–65°C window, making it especially useful where smoke detectors are less effective. The unit can link with up to 40 other compatible alarms so a single event notifies the whole system. Durable ABS housing resists moisture and corrosion. Installation is simple (no hardwiring) and the alarm can be silenced remotely. Supplied: heat sensor, screws, plugs and user manual.

Heiman WS2GW-R is a compact (80 × 80 × 26.5 mm) Wi‑Fi smart gateway for Tuya ecosystems. It bridges 2.4 GHz Wi‑Fi with 433/868 MHz sensors—supporting up to 40 devices (smoke, gas, motion, temperature, leak, door/window). Receive real‑time alerts via the TUYA Smart app, monitor LED status indicators (network, power, device), and create automation scenes. Rated –10 °C to +55 °C, ≤ 95 % RH for reliable home security.

The Heiman HM1RC-W is a compact wireless remote that gives you quick, intuitive control over an interlinked alarm network. Using RF868/RF433 communication it works with smoke, heat, gas and other compatible sensors, letting you test devices, pinpoint which sensor triggered an alert, and silence nuisance alarms with a single press. Its simple button layout and ergonomic shape make everyday operation easy for all household members. The remote is ideal for homes, offices and larger properties where many sensors are installed — it speeds up response, reduces panic during false alarms and helps keep your system reliably maintained.

The WS3MS sensor is a device designed for home use that uses wireless WiFi technology to monitor motion in real time. Thanks to its automatic threshold adjustment technology, it provides high stability of operation and effectively minimizes false alarms. In addition, automatic temperature compensation technology prevents the sensor's sensitivity from dropping due to changes in ambient temperature.
