New Products: Dokodemo Demu, Dokodemo Demu Mini "Programmable wireless unit developed with the concept of enabling data transmission anywhere, equipped with analog and digital I/O ports."

Programmable wireless unit equipped with analog and digital I/O ports, developed with the concept of enabling data transmission anywhere.

The "Dokodemo Demu" compact model (DM-100) is a programmable wireless unit equipped with the "MLR-429," a specific low-power wireless module compatible with LoRa from Circuit Design. It features an Espressif System ESP32 microcontroller (which has built-in WiFi/Bluetooth) along with input/output ports and a temperature, humidity, and pressure sensor (BME280). The program for this product is intended to be created, tested, and written by the customer themselves for operation. Please ensure thorough operation verification of the entire system, including wireless communication. The Arduino bootloader has been pre-installed, allowing you to program it immediately in the Arduino environment after purchase. In addition to the compact model equipped with the MLR-429 wireless module, "Dokodemo Demu" also offers an "LTE-M model" equipped with the LTE-M wireless module LTM-1. What is "Dokodemo Demu"?

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
