  • DHT21 AM2301 Temperature &...

    £3.74

    The DHT21 digital temperature sensor is one of the commonest from the range of DHT temperature sensors and boasts a relatively high temperature measurement accuracy of 0.5oC in 0.1oC steps with a relative humidity accuracy of +/- 3%. It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller...

  • RCWL-0516 Microwave Radar...

    £1.66

    This module has been designed as an alternative to the PIR motion detectors commonly used in burglar alarms. Instead of sensing changes in infrared radio emitted by a moving person this sensor uses a microwave Doppler radar to detect moving objects. It has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from...

  • BF350-3AA Strain Gauge Module

    £4.16

    This strain gauge module uses a BF350 sensor to measure mechanical stresses in solid materials. The module includes an adjustable amplifier circuit to make it suitable for interfacing directly to a microcotrollers ADC input and requires only a single 5V power supply.

    Note that this module should be used for applications where only relative strain measurements are required.

  • BF350-3AA Strain Gauge Sensor

    £1.08

    A resistive strain gauge sensor with a 350 ohm nominal resistance which varies when a force is applied. By measuring the change in the sensors resistance a measurement of the force applied to it can be obtained. Note that strain gauges exhibit small changes in resistance and so this sensor should be used in a Wheatstone bridge...
