Product sensing
With our original communication terminals, we develop systems to achieve the things we wish were possible and then provide thesesystems as an IoT service.
(1) Lead battery sensor
These systems can sense the lifespan (degree of deterioration)and condition of lead-acid batteries and monitor them remotely inthe cloud. All they need is an IoT device, which can be retrofitted,
and the systems don’t require dedicated software, making it easy
to implement IoT. IoT devices communicate via Bluetooth,offering cable-less installation even when monitoring multiple
lead-acid batteries at a single location. IoT visualization allows
recycled batteries to be used safely.

(2)Remote water quality monitoring systems
These systems offer 24-hour monitoring of water temperature andthe amount of dissolved oxygen for terrestrial aquaculture. They
can also be linked with temperature, humidity, image data, andother information to offer easy yet sophisticated water quality
control anytime and anywhere, via smartphone or computer,particularly for closed aquaculture farming such as circulation
filtration farming.

Foodtech business
There are growing concerns about food safety and rising calls for effective hygiene management systems, such as Hazard Analysis
Critical Control Point (HACCP).
In addition, companies are committed to and engaged in saving resources to create a more sustainable society.
Against this backdrop, we have developed Agemono GO, a product using advanced technology to reduce the amount of oil used indeep-frying.

ARM-based CPU module
As an authorized distributor of the ARM-based CPU module manufacturer Toradex©, we single-handedly offer everything from productsales to support. Customers can choose from our lineup of more than 60 types of CPU modules suitable products for their applications
including image processing, AI processing, and ultra-low power consumption. We also develop custom products using these CPU
modules.

Custom Power Supplies
All CRBOX-brand products are customizable and many are used in industrial applications that require reliability, including power supply
devices to meet unique standards such as high-voltage input and chemical capacitor-less. The LX210, an ultra-high-precision isolation
amplifier for insulation applications, is also highly regarded.
In addition to developing high-function custom power supplies, we can propose extra optimizations including those for peripheral circuits
to achieve low-cost, thanks to the many years we have spent cultivating circuit technology utilizing analog and microcomputer
technologies.
