HC-05 Wireless Bluetooth RF Transceiver Master Slave
☛ Master-slave integration 2-IN-1 HC-05 Module: the original chip corresponds to the master-slave integration function. Master-slave integration can switch between master and slave modes. Through AT command setting, you can select master mode or slave mode.
☛ AT Setting: Press the button and power on the module to enter the AT mode. AT commands are executed only in AT mode, which is easy to use. Default baud rate:4800,Default pin:1234, the default name is HC-05.
☛ On-board 3.3V voltage regulator chip, input voltage DC 3.6V-6V; When not paired, current about 30mA (due to LED lights flashing, current in the state of change); After the pairing succeeds, the current is about 10mA
☛ Working status indicator: Fast flashing LED means no Bluetooth connection, slow flashing means entering AT mode, double flashing means Bluetooth is connected and the port is opened.
☛ Tips:Do not connect the power supply to the signal pin, otherwise the module will be directly damaged. The input voltage must not exceed 7V. (Note: this item doesn’t works with iOS.)
☛ It’s ideal replacement to your wired serial connectionSKU: n/a -

HC-SR04 Ultrasonic Sensor HC SR04
The HC–SR04 ultrasonic sensor uses sonar to determine distance to an object like bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. From 2 cm to 400 cm or 1” to 13 feet. Ultrasonic sensors are used typically in applications to measure the level or the distance. Especially in the level measurement ultrasonic sensors are used because they are quick and easy to implement.
