About this item Fun Noise Control: Turn noise control into a fun routine with a traffic light–style visual cue system. Red-yellow-green lights show volume levels instantly, helping students self-regulate without constant teacher reminders and making classroom management smoother. Comfort Monitoring: Built-in temperature and humidity sensors display real-time changes, helping you adjust the environment for better focus and comfort. Ideal for keeping younger learners calm and maintaining a steady classroom atmosphere. Custom Alerts: Set your own limits with an adjustable decibel meter (50–100 dB) and 15 voice levels. When noise climbs too high, a soft red light and gentle “Please keep quiet” reminder restore order without disrupting instruction. Easy Operation: A bright LED display shows readings at a glance, including a noise meter view for quick checks. Simple buttons let you fine-tune alerts in seconds—no complicated setup required, ideal for busy teachers. School-Ready Build: Durable metal housing resists scratches, bumps, and drops, making it reliable for high-traffic educational spaces. Perfect for classrooms, libraries, counseling rooms, clinics, and other quiet-required areas. Show more
