This DHT11 is a temperature and humidity sensor which features a calibrated digital signal output. By using the exclusive digital-signal-acquisition technique and temperature & humidity sensing technology, it ensures high reliability and excellent long-term stability. The DHT-11 uses a resistive-type component for humidity measurements, and a NTC for temperature measurements. The generated signal is connected to a high-performance 8-bit microcontroller, offering excellent quality, fast response, and anti-interference ability.
This kit includes the basic components and PCB to help you make a fully functional metal detector! Simply solder all the components together and you have yourself a metal detector with 5cm sensing range.
Rotary encoders are used similarly to potentiometers. They re different from potentiometers in that an encoder has full rotation without limits. They output gray code so that you can tell how much and in which direction the encoder has been turned. This encoder is especially cool because it has a red/green LED built in, as well as a push-button. Look below for the clear knob that goes with this potentiometer.
