Deviation Alerts: If temperature or humidity exceed set thresholds, a notification is sent to your phone.
Battery Level Monitoring: The remaining battery charge is shown on the display, and a notification is sent to the app before depletion.
Easy Installation: Can be placed on any flat surface or easily mounted on a wall with the included adhesive sticker.
Historical Data: Allows temperature and humidity analysis for up to one year.
Usage Scenarios:
Residential Homes: Monitor indoor climate to ensure a comfortable temperature and optimal humidity level.
Offices and Commercial Spaces: Helps maintain a suitable work environment and protects equipment from humidity or temperature fluctuations.
Children’s Rooms: Ensures an optimal environment for babies, preventing excessive heat or dryness.
Warehouses and Archives: Protects important documents and sensitive items from unfavorable environmental conditions.
Agriculture and Greenhouses: Monitors temperature and humidity fluctuations to optimize plant care.
Pros:
High accuracy – ±0.3°C for temperature and ±2-3% RH for humidity.
LCD screen and mobile app – two ways to check data.
Smart automation – can control other devices (air conditioners, humidifiers, etc.).
Long battery life – operates up to one year on 2 AAA batteries.
Easy installation – can be placed or mounted on a wall.
Wide operational range – up to 1200 m in open space with ZigBee connection.
Alerts for condition changes – notifications when conditions exceed set parameters.
Long-term data storage – access up to a year of historical data.

Cons:
Requires a ZigBee network controller – the sensor cannot connect to a smart system without it.
No built-in Wi-Fi – requires an additional ZigBee interface.
No sound alerts – notifications are only sent to the app.
Batteries may need periodic replacement – while they last up to a year, long-term use may require replacements.

IMOU ZTM1 ZigBee temperature and humidity sensor is an excellent solution for monitoring indoor climate and integrating with a smart home system. Its accuracy, long battery life, and easy installation make it a reliable choice for various applications.
