Devantech SRF01 Single Transducer Ultrasonic Ranger

World beating performance - the SRF01 employs our 2nd generation AutoTune technology which allows ranging all the way down to zero on a single transducer sonar.

Supplied with Mounting Grommet.
For a suitable cable.

Devantech SRF02 High Performance Ultrasonic Ranger

Lowest cost ultrasonic ranger with both I2C and Serial interfaces. New AutoTune algorithms intelligently back the minimum range right up to the transducer ringdown for the very best performance possible, automatically, in the background, and with no calibration cycles necessary.

Additional new commands allow for separate burst and ranging control.

Devantech SRF04
Ultra Sonic Ranger Module

The SRF04 Ultra Sonic Ranger Module is a high quality ultra sonic range finder, which can easily be connected to many microcontroller's to measure/detect the presence of obstacles.

Using a 5V supply and drawing from 30mA typical. to 50mA max. The SRF04 can be connected directly to many micros without the need for a separate power supply.

Ultra Sonic Ranger Module

Devantech SRF08
Ultra Sonic Ranger Module

The SRF08 is an evolutionary step up from the SRF04. It requires less power to operate, has a longer range (up to 6m) and it performs its own internal timing of the return echo. The SRF08 is also fitted with an LDR to measure light levels.

Communication with the SRF08 is via the I2C bus that is available on many popular microcontroller's.

Miniature Size: Only 15mm high - 32mm long - 10mm deep

Devantech SRF10
Ultra Sonic Ranger Module

The SRF10 is a miniature ultrasonic range finder, controlled over a I²C bus which is available on most popular micro controllers, (including AVR devices).

Like the SRF08, the SRF10 will operate up to 6m while performing its own internal timing of the return echo.

Devantech SRF235
"Pencil Beam" Ultrasonic Range Finder.

The SRF235 is a small sonar with an industrial air coupled transducer, giving a very narrow 15° beam width and fast cycling - up to 100Hz update rate.

Working at 235KHz, the SRF235 can be used simultaneously with standard 40KHz rangers without interference.

Devantech CMPS03
Magnetic Compass Module

The CMPS03 Magnetic Compass Module has been specifically designed as a robot navigation aid.

This module can easily be connected to many popular microcontroller's via the I2C bus.

The compass uses two Philips KMZ10A magnetic field sensors that are sensitive enough to detect the Earths magnetic field. The module generates a number that indicates the bearing of the robot in relation to the local magnetic field. This number can then be read by the microcontroller.

TPA81 Thermal Sensor Array

The TPA81 can detect a candle flame at a range 2 meters (6ft) and is unaffected by ambient light and it can also detect body heat!

The TPA81 is a thermopile array that can be used to measure the temperature of 8 adjacent points simultaneously. Moreover if used in conjunction with a servo (to pan the module), a thermal image of a heat source can be built up.
