The new devices come from a variety of suppliers and offer increase distanced capabilities irrespective of colour and surface of the tracked item. They are also designed to operate in both indoor and outdoor environments and satisfy high-speed, small size and low power demands.
The new products include:
• Renesas ISL29501 ToF IC can detect objects at up to 2m providing a cheap solution for distance measurement. ISL29501 offers a full object detection and distance measurement solution when used with an external emitter and photodiode. It is small, low power and provides superior performance.
• ST Microelectronics VL53L1X ToF Nucleo pack is a complete evaluation kit based on the company’s latest FlightSense VL53L1X ToF sensor. The VL53L1X is is a small, rapid ToF sensor accuracy to 4m and features a fast-ranging frequency up to 50 Hz. The technology allows distance to be measured independently of target reflectance by measuring the time light takes to travel to the nearest object and reflect back to the sensor, rather than the amount of light reflected back.
• Broadcom AFBR-S50MV85G evaluation kit contains an NXP FRDM-KL46Z evaluation board and an AFBR-S50MV85G adapter board for out-of-the-box connectivity between the sensor and an MCU board. The device can be used both inside and outside and is optimised for distances of up to 10m. It is intended for industrial sensing and gesture sensing applications that need high speed, small size and very low power consumption.
