Essential for manufacturing that considers environmental concerns and complies with regulations, capable of various measurements/analyses - also selected as a "Zero Emission Challenge Company" by the Ministry of Economy, Trade and Industry.

Our company is in the construction industry, yet we have developed resource exploration, geological survey, and drilling technologies rooted in the mining industry. We have also provided various applied technologies as a resource and environmental consultant. In the environmental field, we can offer a consistent response from investigation to analysis and countermeasures for soil and groundwater contamination. Additionally, we can propose environmental measurements and countermeasures for production sites. In the energy sector, we are working to promote and disseminate geothermal utilization systems that excel in environmental and energy-saving properties. We are involved in numerous large-scale projects, and in geothermal power generation, we have been selected as a "Zero Emission Challenge Company" by the Ministry of Economy, Trade and Industry, which aims to innovate for the realization of a decarbonized society. 【Business Activities】 ■ Resource Consulting ■ Environmental Consulting ■ Energy Consulting *For more details, please refer to the PDF document or feel free to contact us.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
