This Buzzer is suitable for PCB mounting and producing audible tones and frequencies. It can be directly connected to a v micro controller pin. It can be used with arduino as well. It can be used for making DIY robots. This buzzer has loud sound output with low power consumption.

Thermistor are  mostly  used  to monitor the temperature of battery packs while charging,The resistor whose resistance is dependent on temperature There ate two type of thermistors PTC,NTC.PTC  is used as timers in the degaussing coil circuit of most CRT displays. . PTC  is  used  as heater in industryWe can use PTC thermistors as current-limiting devices for circuit protection, as replacements for fuses, NTC  are used to monitor the temperature of an incubator.

This a compact piezoelectric buzzer designed for use in electronic alarm and notification systems. Housed in a cylindrical package measuring 16mm in diameter and 14mm in height, this buzzer delivers a loud sound pressure level of ≥90 dB(A) at 10 cm, making it highly suitable for audible alerts.

Operating across a wide voltage range of 3V to 7V peak, with a rated voltage of 5V peak, it performs best at its resonant frequency of 2048 Hz, producing a clear and penetrating tone. The buzzer exhibits a DC resistance of 45 ±6 ohms and supports a broad operating temperature range from -40°C to +85°C, ensuring reliable performance in both indoor and outdoor environments.
