DC5V Humidifier USB Spray Module DIY Incubation Experiment Equipm 108KHz(mist maker)
[Ultrasonic Sensor] Description This DC Ultrasonic Humidifiers Power Circuit Board with Atomizing Chip Moisture Film Humidification atomization machine consists of an atomization plate tablet with a diameter of 20mm. This Ultrasonic Humidifier Piezoelectric Transmitter module works on the principle of cavitation produced by sound waves. Just provide the DC 3V to 5V power supply it will turn into a mini ultrasonic atomizer. As sound waves contain compression and rarefaction. Due to extremely rapid movement, water droplets can no longer sustain their liquid state and get converted into vapor immediately. This vibration is produced by a piezoelectric filament.

2 Channel 5V Relay Module with Optocoupler
[Relays] This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). It has a 1×4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays. The pins are marked on the PCB:- GND – Connect 0V to this pin. IN1 – Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V IN2 – Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V VCC – Connect 5V to this pin. Is used to power the opto couplers Specification:- High current relay, AC250V 10A, DC5V 10A 2 LEDs to indicate when relays are on Works with logic level signals from 3.3V or 5V devices Opto isolation circuitry * Product Images are shown for illustrative purposes only and may differ from actual product.
