SIM-built temperature and humidity meter EZ-101A without power or Wi-Fi required.
EZ-101A
No need for power, Wi-Fi, or installation. Just place it to record temperature and humidity in the cloud and monitor remotely.
The EZ-101A is an LTE-M communication temperature and humidity meter with a built-in IoT SIM. It requires no power installation, Wi-Fi, or router; simply place it on-site to start measuring. It measures temperature and humidity every five minutes and automatically sends the data to the cloud every hour. You can check multiple remote locations collectively from a smartphone or PC web browser, and there is no need to install a dedicated app. While out of range, it can store up to 30 days of data in the unit and send it all at once after recovery, ensuring no gaps in the records. It operates for over five years (design value of six years) on a built-in lithium battery alone. With an IP65 design, it can be used outdoors under eaves or in refrigeration and freezing equipment, and it has been confirmed to operate at temperatures below -20°C. It supports email notifications with specified duration for threshold exceedances, automatic calculation of heat index (simple WBGT), dew point, and VPD, as well as Excel and PDF output, and integration with existing systems via API/Webhook. This is a monthly service that includes equipment, communication, app, and warranty, so there is no need to purchase the equipment.
