Hall Effect Sensor – Unipolar – WSH130NL
WSH130NL is designed to integrate Hall sensor with output driver together on the same chip, it is suitable for speed measurement, revolution counting, positioning, and contactless switches. It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller and a open-collector output driver capable of sinking up to 20 mA current load. An on-chip protection resistor is implemented to prevent reverse power fault.
The temperature-dependent bias increases the supply voltage of the hall plates and adjusts the switching points to the decreasing induction of magnets at higher temperatures. Subsequently, the output can keep switching on/off on more precise switch point regardless to the ambient temperature. WSH130NL are rated for operation over temperature range from -40℃ to +125℃ and voltage ranges from 2.4 V to 26 V.

HC-12 433Mhz SI4463 Wireless Serial Module
HC-12 wireless RF UART communication module is a new generation of multi-channel embedded wireless data transmission module. The Radio frequency of 433.4 473.0MHz, can be setting a communication channel, step is 400kHz, a total of 100 channels. The module maximum transmit power is 100mW (20dBm), and -116dBm receiver sensitivity air of the 5000bps baud rate, communication distance about 500 meters.
The module adopts a stamped hole encapsulation method, which can be welded. The module size is 27.4mm*13.2mm *4mm (including antenna seat, not including the spring antenna), which is convenient for the customer to be embedded in the application system. The module has a PCB antenna seat ANT1, users can use the coaxial cable, the use of 433MHz band external antenna.
The module also has antenna welding hole ANT2, convenient user welded spring antenna. The user can choose one kind of antenna according to the request. The module contains MCU, users do not need to program in addition, just send and receive
UART data. The module uses a variety of UART transmission mode, the user can choose
according to the requirements of the use of AT command. The four UART modes of FU1, FU2, FU3, FU4, the average operating current is 3.6mA, 80A, 16mA and 16mA, the maximum operating current is 100mA (full power transmit state)Â HC12 Module is based on the SI4463 EZRadioPro family chip by SiLabs. This module offers a wireless data transmission and reception range of approximately 1 km in the open air. Its a low power radio chip that is ultra-easy to use.
This module has an onboard STM8S003F3P6 MCU which is communicating with the SI4463 so that the user can communicate with the HC12 module using a simple TTL 2 wire serial interface (RX, TX, GND).
