Passage People Counting in A Cost-Effective Way
With bi-directional detection using dual PIR sensors, the passage people counter brings applicable accuracy and redefines the way you track foot traffic in a cost-effective way.
Two Models for Different
Temperature Monitoring Needs
Milesight offers two models, TS201 and TS201-TH, each designed to work with a different type of probe to suit varied temperature monitoring scenarios
Meet Hazard Analysis and Critical Control Points (HACCP) Requirements
Complies with EN12830 Standard
Specialized for Cold Chain Application
Aside its cutting edge sensing technology, TS201 is designed specially for professional cold chain applications, where even the extreme temperatures would not affect its tremendous accuracy.

Detachable Probe for Independent Calibration
Both Milesight TS201 and TS201-TH feature detachable sensing probes that can be calibrated independently. This ensures stable and accurate temperature sensing and monitoring, making them ideal for cold chain and other temperature-sensitive applications
Glass Bead Thermal Buffer Bottle
An optional accessory is available to buffer readings against temporary shifts in air temperature resulting from the opening of doors or loading coolers. This is particularly useful for pharmacies, doctor’s offices, and other settings that may undergo significant, temporary changes in temperature

Real-time Alerts
Users are able to receive immediate alerts for any potential threats, such as temperature spikes or opened doors. Data is swiftly transmitted to the cloud for easy access and retrieval, reducing inventory loss
It is advisable to place the device outside of the refrigerator
TS201-TH does not support Milesight IoT Cloud
Pin-point Temperature Anomalies
Accurately spot temperature anomalies through receiving alerts sent from the sensing probe with its own identification number
The identification number helps to identify if the probe has been calibrated
Waterproof Ratings and Unique Battery Compartment Design
With an IP67 rating and uniquely designed rotatable battery cover, Milesight TS201 is designed to ensure waterproof functionality, providing reliable performance even in challenging environments, while allowing multiple installation methods like wall mount, zip tie, and magnetic mount
