Datasheet

Renesas has announced the availability of its Detect it! solution kit. The Detect it! kit is designed for detector applications and provides ready to use demonstrators for the most typical detectors used in security and fire protection systems. Detect it! has four demonstrator hardware boards, a motion detector, smoke detector, carbon monoxide detector and a glass-break detector.

The solution kit provides a complete platform for Renesas’ RL78/I1D MCU group, devices which offer a comprehensive set of analogue features. The small 48-pin package includes 4 op amps, 2 comparators and 17 input channels for the 12-bit ADC. The RL78/I1D has smart peripherals that are able to work without CPU intervention and offers low power modes.

The smart peripherals can transfer data, compare data, perform addition and subtraction and link one peripherals operation to another peripheral. Power consumption has also been further reduced compared to previous generations, achieving 124µA at 1MHz in operation. Fast wake-up time reduces power consumption even more and enables the device to react faster, which is especially beneficial for communication protocols.

Each of the boards provides a solution for the associated detectors. The smoke detector senses smoky environments by the scattering of an IR signal in a smoke chamber. Motion is detected using PIR technology. The glass-break detector analyses sounds and can differentiate window-break sounds from the surrounding environment. The carbon monoxide detector uses a chemical sensor to measure the concentration of the gas in the surrounding air and generates an alert if the levels are dangerously high.

The documentation provided within the kit guides the user and explains the board behaviour in detail.

The Detect it! kit is ready for use out of the box. Users simply choose the board and insert a battery (included in the kit), follow the quick start guide and can get a detector working in less than one minute. The kit includes the source code of the demonstration sample programmes, the environment development installer of IAR Embedded Workbench, the Gerber files and the schematics, and a comprehensive user manual. As this kit was specifically designed for detectors, it brings time and cost saving advantages to developers in this field.

The Detect it! kit is available directly from Renesas or through distributor channels. The part number is YDETECT-IT-RL78.
