Grove Piezo Vibration Sensor is suitable for measurements of flexibility, vibration, impact and touch. The module is based on PZT film sensor LDT0-028. When the sensor moves back and forth, a certain voltage will be created by the voltage comparator inside of it. Therefore, outputs high & low levels. In spite of the fact that it has a high receptivity for strong impacts, a wide dynamic range (0.001 Hz~1000 MHz) also guarantees excellent measuring performance. Finally, you can adjust its sensitivity by adjusting the potentiometer with a screw.

The JOY-iT R301T fingerprint sensor module is capable of image collection and algorithm calculation due to this integrated chip. Another remarkable function of the sensor is, that it can recognize the fingerprint in different conditions, for example humidity, light texture or changes of the skin. This offers a very wide range of possible applications to secure locks and doors among others. The chip can send data via UART, TTL serial and USB to the connected controller. Specifications Model JP2000 sensor Chip 32 Bit ARM Cortex-M3 Chip storage 96 kB RAM, 1 MB Flash Power supply 4.2-6.0 V Working current Typical: 40 mAPeak: 50 mA Logic level 3,3/5 V TTL Logic Fingerprint storage capacity 3000 Prints Matching mode 1:N Identification1:1 Verification Adjustable security level 1 - 5 levels(default security level: 3) False acceptance rate < 0.001%(on security level 3) False acceptance rate < 0.1%(on security level 3) Response time Pre-treatment: < 0.45 sMatch: < 1.5 s Baud rate support 9600 - 921600 UART communication No parity, Stop Bit: 1 Dimensions 42 x 19 x 8 mm Included 1x Fingerprint sensor COM-FP-R301T 1x Cable Downloads Datasheet Manual

This ultrasonic distance sensor (ME007-ULA V1) offers high performance with a robust, waterproof probe. Operating on the principle of ultrasonic echo ranging, the sensor determines the distance to a target by measuring the time elapsed between sending a pulse and receiving the echo. Its non-contact design allows it to detect a wide range of materials, including transparent or non-ferrous objects, metals, non-metals, liquids, solids, and powders. Specifications Detecting Distance 27~800 cm Output Interface RS232, Voltage Analog Operating Voltage 5-12 V Average Current <10 mA Operating Temperature −15~60°C Dimensions 60 x 43 x 31 mm
