A-Star 328PB Micro - 3.3V, 12MHz

The Sensor of Image Charmed Labs Pixy 2 CMUcam5 is smaller, faster and more capable than the original Pixy. Like its predecessor, Pixy2 can learn to detect objects, just by pressing a button. In addition, Pixy2 has new algorithms that detect and track lines for use with line following robots. The new algorithms can also detect intersections and "traffic signs". Traffic signs can tell your robot what to do, such as turning left, turning right, slowing down, etc.

The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.

Bi-directional Logic Level Converter 4-channel by I2C BSS138

This is a DC-DC buck-mode power module, with input voltage range of 3V - 15V and fixed voltage / current at fixed 5V / 600mA . Working frequency can reach 0.5 MHz . The module has high conversion rate and small size, easy to incorporate.

This small digital distance sensor detects objects between 2 cm and 10 cm apart. With its fast response time, small size and low current consumption , this sensor is a good choice for detecting non-contact objects in compact PCBs facilitating integration into your project.

The Current Sensor 70A is a great option for those looking for equipment to measure current up to 70A and that is non-invasive.

Monitor the consumption of any appliance, electrical circuit or office equipment (lighting, sockets, security systems, heaters, air conditioning, etc.) individually with this compact device that works via Wifi so you can monitor everything through your smartphone.

The CNY70 has a compact construction where the emitter and receiver are arranged in the same direction to detect the presence of an object using the object's reflective IR beam.

The Module KA2284 is a Battery, Power and Audio Level Indicator.

This UV Sensor is capable of detecting UV solar radiation using a simple UVM-30A chip. It can be easily configured for projects with Arduino to monitor UV Index, analyze UV-A lamps or DIY projects as plant growth analysis.

The 5-Channel Infrared Detector Sensor Module is designed to optimize robotics and electronics projects.
