【400KVDC】DC 3V-6V to 400kV 400000V Boost Step up Power Module High Voltage Generator.
【Compatible】Input voltage: DC 3 V to 6 V;Input current: 2 A - 5 A;High pressure type: the type of pulse current;Output voltage: 400000 v(Please pay attention to safety)
【Design compact】High pressure discharge distance between: 10 mm - 20 mm;The output high voltage wire length: 100 mm; Input power cord length: 100 mm (the red line is positive).
【Easy operation】Power must be adjusted to a suitable distance to the high-voltage output line, battery capacity is proportional to the distance and the use of the high-pressure arc ( not a voltage as high as possible , you must provide enough current ) .
【Note】 Experimental test of the arc distance from short to long , Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module.

Contact Water/Liquid Level Sensor, This is a photoelectric water liquid level sensor that is operates using optical principles. Open collector output mode, suitable for connecting various circuits and product applications.
The sensor has no mechanical parts, requires no additional adjustment, and has high sensitivity, low power consumption, corrosion resistance, high pressure resistance, high temperature resistance and chemical stability.
This sensor probe is small in size and has a structure that can be placed up, down, laterally, and diagonally in multiple orientations to detect solution spillage, dryness and horizontal level. Can be used as a reminder and alarm function.
The sensor has a DIP switch. The DIP switch controls the output voltage (high level) of the signal terminal (green line). When the DIP switch is dialed to 5V, the high level is 5V. When the DIP switch is dialed At 3V, the high level is 3.3V.
Compatible with Arduino motherboard and Raspberry Pi motherboard. for Automatic Irrigation Systems, Aquariums, Plants, in The Garden, in Agriculture etc.

TCA9548: TCA9548A 8 Canale I2C IIC Multi-Channel Expansion Board 1-to-8 TCA9548 8-Way
【Compatibile】L'adattamento è collegato a un dispositivo I2C con indirizzi multipli identici sulla porta I2C sulla scheda principale per la comunicazione normale e l'uso. Compatible with IIC bus and system management bus (SMBus), active low reset input, support for hot insertion, low standby current, no glitch during power-up, support for voltages between 1.8V, 2.5V, 3.3V and 5V buses Level shifting.
【Design compatto】There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switch that can be controlled by I2C bus. Questo significa che dopo 1 expander is transferred, 8 indirizzi identici possono essere collegati alla porta I2C. Il dispositivo è anche in normale uso. Il default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77 secondo to your needs.
【Descrizione】The switch has a turn-on gate so that the VCC pin can be used to limt the maximum high voltage through the TCA9548A. Limiting the maximum high voltage allows different bus voltages to be used on each channel pair so that 1,8 V, 2,5 V or 3,3 V components can communicate with 5 V components without any additional protection, for each channel, external pull-up resistors the device pulls up voltage to the desired voltage level. Tutti i pin I/O sono 5 V senza tensione.
【High performance】In teory, 8 expanders can be accaded in the address of 0x70~0x77, and each expander can connect 8 devices with the same address. Questo realizes the same I2C port and connects 64 devices with the same address and uses them normally. Molto potente!
