3 PCS Electronic Accessories: 1 x humidity sensor with humidity sensitive resistor & 2 x Digital 2 Channel Square Wave Pulse Signal Generator ule
Measurement of humidity, humidity sensor, humidity detection, with a relay output, direct power control equipment
using high-quality HR202 humidity sensor;
the comparator output directly drive the relay, the 220V AC or other equipment;
with a potentiometer to adjust temperature detection threshold

Colour:blue
Digital 2 Channel Square Wave Pulse Signal Generator ule:
Digital square waveform generator ule support 1Hz-150KHz frequency and 0%-100% duty cycle adjusting independently through the on-board momentary push button.
Dual channel fequency signal and duty cycle complementary output, easier to control.
DC5-30V wide voltage input(support micro-USB 5V input),3 digit LED display the parameter easy to read, serial communication interface easy to connect and controlled by MCU.
Used as square wave source for instrument testing,driving the stepper motor, PWM control the motor speed / LED light brightness.
