SRF005 Datasheet | Revolution Education

SRF005 ULTRASONIC RANGE SENSOR Specification: The SRF005 ultrasonic range sensor detects objects in it’s path and can be used to calculate the range to the object. It is sensitive enough to detect a 3cm diameter broom handle at a distance of over 3m. Voltage Current Frequency Max Range Min Range Sensitivity Input Trigger Echo Pulse Small Size - 5V - 30m A Typ. 50m A Max. - 40KHz -3m - 3 cm - Detect 3cm diameter broom handle at > 3 m - 10u S Min. TTL level pulse - Positive TTL level signal, width proportional to range. - 43mm x 20mm x 17mm height The module can be used in two different modes: Single Pin - Single microcontroller pin (08M, and all M2 and X2 parts) Dual Pin - Separate PICAXE microcontroller trigger and echo pins Most users using the latest generation (M2 and X2) PICAXE parts should select ‘single pin’ connection mode. Single Pin Connection Mode: The PICAXE-08M and all M2/X2 parts have bi-directional pins, so the SRF005 can connect to a single i/o pin. There are two way to achieve this connection on the SRF005, via the 5 way header or via the 3 way header. The 3 way header is designed to be patible with ‘servo extension leads’ (e.g. part DAG001) so is often the preferred method on new designs. The 5 way header is patible with older SRF005 modules/PCBs. Using the 5 way header (note +5V and 0V are marked on the SRF005): +5V Connect to 5V Not used Do not connect Signal Connect directly to the PICAXE pin Mode Connect to 0V 0V Connect to 0V Using the 3 way header (note SIG and 0V are marked on the SRF005): Signal (SIG) Connect directly to the PICAXE pin +5V Connect to 5V 0V Connect to 0V When using the 3 pin header you MUST also solder a wire link between the mode and 0V on the 5 way header (ie a wire link between pads 4 and 5 on the 5 way header). Take care not to overheat, and therefore damage, the solder connection pads whilst making connections. revolution Revolution Education Ltd. Email: info@rev-ed.co.uk Web: .picaxe.co.uk V3.0...
