SEZO HM
Hatch and Door Monitoring Sensor
SEZO HM is a compact sensor designed for safeguarding critical technical infrastructure in both outdoor and indoor environments. It monitors the opening of manhole covers, doors, and gates, provides anti-tamper protection, and transmits data to the user’s server. The device operates using LTE-M technology.
MONITORING HATCH OPENINGS
SEZO HM provides information on the opening of manhole covers, doors, and other structural barriers through the use of a limit switch on a cable. This enables the sensor to be used in hard-to-reach places, allowing for optimal placement of the switch for hatch or door monitoring and the sensor relative to the range of wireless communication. This way, the sensor supports the management of urban, industrial, and retention infrastructure, among others. SEZO HM offers extensive capabilities for expanding the range of measurements.
LTE-M TECHNOLOGY
LTE-M is a low-power, long-range network specifically designed for IoT devices to connect directly to the 4G network. It supports high data transfer speeds, enabling real-time communication, which is beneficial for asset monitoring.
PLATFORM INTEGRATION
SEZO HM is integrated with the Orange Live Objects platform, facilitating the viewing and analysis of data collected by the device through easy USB configuration or pre-configuration according to customer requirements. It can also connect to other existing platforms used by your company, thanks to the ability to easily set the network server, such as The Things Stack or Chirpstack. A decoder is available for download on SEZO’s GitHub.

Application Examples
Manhole Cover Monitoring
SEZO HM can be installed in sewer manholes to monitor their opening and closing. This allows urban infrastructure managers to respond quickly to unauthorized openings, preventing theft and vandalism.
Telecom Infrastructure Security
The device is ideal for monitoring hatches and doors in telecommunication equipment enclosures. Detecting openings and tampering helps secure critical network points.
Water Meter Well Monitoring
SEZO HM can be used to monitor water meter well covers, enabling quick detection of openings and securing access to water infrastructure.
Waste Disposal Site Security
Installing sensors on the hatches and gates of waste disposal sites allows for remote access monitoring, crucial for maintaining security and regulatory compliance.
Pump Station Monitoring
The device can monitor access to water and sewage pump stations, providing immediate alerts for unauthorized access attempts or malfunctions.
Warehouse Space Management
SEZO HM can be used in warehouses to monitor the opening of doors and gates, helping secure stored materials and optimize space management.
