Our specialists opt for sensors that measure temperature and humidity with high energy efficiency. These devices are batteryoperated and do not put a strain on the vehicle's electrical system. RISK Electronics experts place them in locations away from direct sunlight. This ensures that the measured indoor temperature data is not distorted by the heating effect of direct sunlight. Additionally, the sensors are installed in inaccessible areas within the vehicles to prevent tampering by passengers with inappropriate behavior. The chosen devices have a long battery life, enabling them to operate efficiently for at least 5 years. This way, battery replacement, which involves costs and labor, occurs over longer intervals.
