20Pcs Soil Hygrometer Humidity Detection Moisture Sensor For Arduino Description: This is a summary of the soil moisture sensor can be used to detect moisture, when the soil is dry, the module outputs a high level, whereas output low. Using this sensor make an automatic watering system, so that your garden plants without people to manage. Operating voltage: 3.3V~5V. Adjustable sensitivity (shown in blue digital potentiometer adjustment) Dual output mode,analog output more accurate. A fixed bolt hole for easy installation. With power indicator (red) and digital switching output indicator (green). Having LM393 comparator chip, stable. Panel PCB Dimension: 3cm x 1.5cm. Soil Probe Dimension: 6cm x 2cm. Cable Length: 21cm. VCC: 3.3V-5V. GND: GND. DO: digital output interface(0 and 1). AO: analog output interface. Instructions for Use: 1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil. 2. Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low. 3. The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture. 4. The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment. 5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture. Package Included: 20 x Soil moisture detector module 20 x Probe 20 x 2P Jumper Cable

Description: Transparent A3 Inkjet Laser Printing Film can be used to make stencil in screen printing, hot stamping and pad printing. Specifications: Color: Transparent Size: 42 x 29.6cm Features: - ASC Non-Waterproof Ink-Jet and Laser Printing Film is a specially coated, clear film that absorbs quick drying ink, and controls the shape of fine lines and half tones; - It can be used to make stencil in screen printing, hot stamping and pad printing. - Ink-jets achieve better quality because heat isn't used to set the ink. - This kind of film is only coated on one side. Print on the coated (matte) side of the film! - If you print on the glossy uncoated side, the ink will not dry because it is not absorbed by the coating. Package Included: 20 x Printing Plate-Making Notes 1.This film also can be used in your laser printer. 2.Your wet finger will stick to the coated side. 3.Printing side is the non-smooth side with coating solution.
