This module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent…
The LM2596 regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step−down switching regulator (buck converter).
This is a 28YBJ-48 Stepper Motor with Gear Reduction, so it has good torque for its size, but relatively slow motion. These motors/drivers are made by the millions for A/C units, fans, duct controls etc. which is why they are so inexpensive. Available in 5V.
Flow adjustable water pump is designed fully submersible for both fresh water and saltwater,extremely quiet operation,completely submersible motor,low power consumption and submersible use only and low rate is adjustable with knob in front of the pump
Used to trigger the effect of various vibration, reported the theft alarm, intelligent car, electronic building blocks, etc. Please note that this module in the induction to the small vibration triggered when time is short, not enough to drive the relay, according to some people can be directly connected to the relay module, use the effect not beautiful.
DS18B20 temperature sensor probe chip with high-quality stainless steel anti-rust waterproof probe housing. Ideal for getting soil temperature, Arduino and other development systems.
The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.
DS18B20 temperature sensor probe chip with high-quality stainless steel anti-rust waterproof probe housing. Ideal for getting soil temperature, Arduino and other development systems.
This thermocouple is designed with fork terminals. Specially designed for digital thermometer which has k type sensor, suitable for measuring liquid or others high-temperature applications.
Utilized in high-end consumer, commercial, and military-grade applications for extreme performance and maximum energy efficiency, TEC1 Peltier Modules provide unmatched temperature differentials (DTmax) in cooling or heating applications.
The DS1307 is a low power, with 56 bytes of non-volatile RAM BCD code clock calendar real-time clock chip, the address and data transmission through the two-wire bidirectional serial bus, the chip can be seconds, minutes, hours and other information , the number of days in each month can be adjusted automatically.
