Temperature sensor for temperature management IoT system [Hakarondo]

It is designed to operate in a HACCP-compliant environment and is intended for use in a store environment.
We have developed a new series of temperature sensors, "Hakarondo~"

(This product was jointly planned by NEC Solution Innovators, TDI Product Solutions, and Shinko Shoji.)

What Hakarondo can do to solve our customers' problems and contribute to them

Shinko Shoji believes that the following are some of the challenges faced by food stores and factories:

• Responding to changes in the business environment due to the COVID-19 pandemic
• Automation and IoT to address labor shortages
• Stabilizing store and factory operations and minimizing operating costs
• Complete elimination of risk
• Compliance with HACCP legislation

One solution to these problems is to build a temperature control system, and the optimal device for this is the "Hakarondo."

We offer two products: multi-channel temperature sensors and single-channel temperature sensors.

Common features of both products

• HACCP compliant operating environment: -30℃ to +60℃
• Wireless communication: 920MHz band specific low power radio
• Long battery life (*1)

Multi-channel temperature sensor features

• Sensor probes can be mounted on up to 6 channels
• Sensor probe can be freely selected from 1m, 5m, 10m, and 15m
• Wireless relay function

Multi-Channel Temperature Sensor
SMART-AT2

1-Channel Temperature Sensor
SMART-TM2

*1: Temperature measurement interval and data transmission interval are 10 minutes each.
SMART-AT2 lasts 6 years in -30℃ environment, 7 years in -20℃ environment, and 9 years in 20℃ environment
The SMART-TM2 is expected to last 8 years in a -30°C environment, 10 years in a -20°C environment, and 12 years in a 20°C environment.
