SONOFF ZigBee SNZB-02D Temperature and Humidity Sensor 2-PackMonitor temperature and humidity in different rooms. The Sonoff sensor provides precise readings that are updated every 5 seconds. It also allows you to remotely monitor temperature in real time and sends notifications in the app when the set temperature is exceeded. Additionally, it stores data in the cloud, giving you convenient access to your measurements.Various ApplicationsThe Sonoff sensor is ideal for rooms with an area of up to 120 m. The product is suitable for use in places such as terrariums, wine cellars, music stores, incubators, greenhouses, etc. You can also use it at home, for example, in a child’s room.High AccuracyThe device is equipped with a Swiss hygrostat that measures temperature and humidity with an accuracy of ±0.2°C/RH. Additionally, readings are updated every 5 seconds, keeping you constantly informed. You can also switch the temperature units between °C and °F.Convenient operationThe sensor is controlled via the app. This allows you to easily view notifications, such as when the temperature exceeds a set limit. What’s more, you can add the device to Home Assistant via eWeLink or use it alongside other smart home devices—when the humidity level drops below 40%, the humidifier will turn on automatically. The Sonoff SNZB-02D also supports Amazon Alexa and Google Home, so a simple voice command is all it takes to check the temperature or humidity in a given room.Wide CompatibilityYou can connect the Sonoff SNZB-02D to a variety of devices. The sensor supports Zigbee gateways that use the 3.0 protocol. As a result, it’s compatible with the NSPanel Pro wall switch, the Sonoff Zigbee Bridge/Pro smart hub, the Sonoff ZBDongle-P/E dongle, and the Amazon Alexa system with a built-in Zigbee hub.Convenient Access to DataDo you want to store your recorded measurements? With the Sonoff SNZB-02D, you can easily access them. The eWeLink app allows you to save readings, so you can check measurement results for a specific hour or day at any time and then export them. Additionally, your measurement history is available for six months. To access this history, you’ll need both the app and a Sonoff gateway.3 Mounting OptionsYou can mount the sensor in 3 different ways, so you can choose the one that works best for you. Thanks to the built-in stand, you can place the device on a desk or countertop for quick access to your readings. The magnetic design also allows you to attach the SNZB-02D to a metal surface, such as a refrigerator. You can also mount the sensor on a wall using a 3M adhesive sticker.Included temperature and humidity sensor x2 user manual Manufacturer Sonoff Model SNZB-02D Color white Wireless connection Zigbee 3.0 Operating humidity 5–95% RH Material PC + LCD Power supply CR2450 battery (3 V) Operating temperature -9.9 – 60°C Battery life 2 years Dimensions 62.5 × 59.5 mm

IMOU Home-Alarm-Kit-11-Ranger-2C Alarm SystemThe comprehensive IMOU Home-Alarm-Kit-11-Ranger-2C alarm system combines the ZG2 smart gateway, motion and door/window sensors, remote controls, a siren with a volume of up to 100 dB, and the 3 MP Ranger 2C camera to create a cohesive home security ecosystem. Zigbee and Wi-Fi connectivity, a sensor range of up to 200 m in open space, and up to 2 years of battery life make the system reliable and convenient for everyday use. Integration with the app enables full control, instant notifications, and security management from anywhere.Smart Control Center – ZG2 GatewayThe ZG2 gateway serves as the central hub of the entire system, allowing you to add, manage, and control Zigbee devices. It transmits all alarm events to the Imou cloud and directly to the user’s app, giving you a constant overview of the situation at home. It supports up to 16 slave devices and allows you to quickly arm or disarm the system with a single button. It features a clear LED indicator showing operational status and offers flexible installation—on a desk or wall. It operates on the 2.4 GHz Wi-Fi and Zigbee 3.0 standards at temperatures ranging from -10 to 55°C.Precise motion detection – ZP1 sensorsZP1 motion sensors use infrared to detect human presence, working effectively even in complete darkness. The detection range is 8 m, and the viewing angle is 90°, allowing you to cover key areas of a room. Thanks to 360° adjustment and magnetic mounting, installation is quick and convenient. Low power consumption and a high-capacity CR123V battery ensure up to 2 years of operation under standard use. The sensor generates minimal data traffic, ensuring privacy and stable operation.Door and Window Opening Monitoring – ZD1 SensorsZD1 sensors monitor the status of doors, windows, cabinets, or drawers, detecting when they are opened by the separation of a magnet from the sensor. The alarm is triggered at a separation of just 25 mm, allowing for a quick response to unauthorized access. The tamper-proof design and low-battery warnings enhance safety. The devices communicate over distances of up to 200 m and operate for up to 2 years on a single battery, reducing the need for maintenance.Immediate response – ZR1 siren and convenient control – ZB1 remotesThe ZR1 alarm siren generates a sound of up to 100 dB, effectively deterring intruders and immediately alerting you to a threat. In addition to its alarm function, it also acts as a Zigbee signal booster, increasing the range and stability of communication by up to 50 m. It can be mounted on a wall or ceiling, and its functionality also includes visual alerts and notifications sent to the app. The ZB1 remotes, on the other hand, allow for quick system management without having to reach for your phone. They offer four operating modes: home arming, away arming, disarming, and SOS alarm. They support single-click, double-click, and long-press functions, allowing you to customize their operation to your needs. Thanks to low-power Zigbee technology, they operate for up to 2 years on a CR2450 battery, and their compact design allows for magnetic mounting or installation using 3M tape.Smart Monitoring – Ranger 2C CameraThe 3 MP Ranger 2C camera works with sensors to create an advanced monitoring system. Upon detecting an event, it automatically turns toward the alarm and begins recording, while the tracking feature allows it to follow a moving object. Thanks to scene integration in the app, the camera becomes an active security element, providing visual confirmation of events.Advanced automation and minimization of false alarmsThe system utilizes multi-point correlations between sensors and the camera, enabling immediate response and intelligent operation. Triple verification—motion sensor, door sensor, and camera—significantly reduces the number of false alarms. The ability to schedule automatic arming and disarming eliminates the need for daily manual operation and enhances user conv
