Visualize "Heat Index" at multiple locations through the cloud.

SisMil combines JIS-compliant WBGT measurement with cloud technology. It monitors heatstroke risk at work sites in real-time to protect worker safety.

SISMIL: Environmental Monitoring Cloud

What is SisMil?

An environmental monitoring solution that combines high-precision WBGT measurement using black-globe sensors with LoRa-based long-range wireless communication.

Centralized Cloud Management

Monitor measurements from multiple sites on your smartphone or PC. No need to visit sites manually.

JIS-Compliant Reliability

omplies with JIS B 7922:2023. Measures high-precision WBGT (Heat Index) to support safety management.

Alerts & Report Emails

Receive email notifications when WBGT exceeds set thresholds or for hourly measurement updates.

Easy Setup & Wide Coverage

Uses the LoRa method, which is resistant to obstacles. 98% of clients set up the system themselves.

Seamless Process from Measurement to Visualization

1

Measurement (Sensor Nodes)

Measures Heat Index (WBGT) using electronic wet-bulb globe thermometers (JIS B 7922:2023 compliant).
2

Transmission (Gateway)

Sends data via LoRa wireless (up to 500m line-of-sight). Uploads to the cloud via LTE (SIM included) or wired LAN.
3

Management & Visualization (Cloud)

Graph display, CSV export, and alert notifications. Manage all locations centrally.
