Humidity and Temperature Sensor - DHT20
The DHT20 is a factory-calibrated digital humidity and temperature sensor with an I²C interface. An upgrade to the popular DHT11/DHT22 series, it provides reliable environmental measurements without requiring additional calibration or external components. Key Features I²C Digital Output – Stan...
Humidity and Temperature Sensor Module
Measure temperature and relative humidity with this simple, Arduino-compatible sensor module based on the DHT22. With just three connections (GND, power, and data), you can read both temperature and humidity from a single I/O pin on your microcontroller. An Arduino library is available to make in...
Hummingbird 2-Wire Extension
·
A one-metre extension lead for the two-wire Hummingbird parts — single-colour LEDs, gear motors and vibration motors. Worth having on hand once student builds grow taller than the standard 50cm leads allow. Fits the Hummingbird Bit and the Hummingbird Duo.
Hummingbird 3-Wire Extension
·
One metre of extra reach for three-wire Hummingbird sensors, so a light, sound, dial or distance sensor can sit where the model actually needs it rather than beside the controller. For use with the Hummingbird Bit and the Hummingbird Duo.
Hummingbird 4-Wire Extension
·
A one-metre extension cable for Hummingbird tri-colour LEDs, which need four conductors rather than the usual two. Handy when the LED belongs at the far end of a large model. Compatible with the Hummingbird Bit and the Hummingbird Duo.
Hummingbird Battery Pack
·
A 4 x AA battery holder with an on-off switch, made to power the motor supply on a Hummingbird controller. Use it when a student build needs to drive around the room instead of staying tethered to a USB lead. Works with both the Hummingbird Bit and the Hummingbird Duo. Batteries are not included ...
Hummingbird Bit Controller
·
The controller board at the heart of the Hummingbird Bit system, sold on its own as a spare or as a way to add another build station to a class set. A BBC micro:bit is required and is not included — the micro:bit slots into the edge connector and acts as the brain, while the Hummingbird board sup...
Hummingbird Bit Premium Kit (micro:bit Not Included)
·
A BBC micro:bit is required and is not supplied with this kit. The Hummingbird Bit controller runs on a micro:bit, so add one to your order — we stock them separately. The Hummingbird Bit Premium Kit is a box of lights, sensors and motors that students bolt onto whatever they can find: cardboard,...
Hummingbird Dial Sensor
·
A rotary dial that reports its position as a value from 0 to 100. Students use it to set a speed, dim a light, pick a mode or steer a servo by hand — the simplest way to put a person in the loop of a Hummingbird program. Connects to a sensor port on the Hummingbird controller. Works with the Humm...
Hummingbird Distance Sensor
·
Measures how far away an object is, so a Hummingbird build can dodge obstacles, count people walking past or feel its way around a maze. Recommended for the Hummingbird Bit; it is not supported on the older Hummingbird Duo. Plugs into a sensor port on the Bit controller and reads out in code as a...
Hummingbird Duo micro:bit Adapter
·
This adapter allows your Hummingbird Duo to work with the micro:bit. Simply plug it into the back of the Hummingbird, write programs in the block-based MakeCode environment, and download them onto the micro:bit. Once the code is downloaded, unplug your Hummingbird robot from the computer and your...
Hummingbird FS90 Micro Servo
·
The little servo in the Hummingbird range. Lower torque and lower cost than the full-size units, and small enough to hide inside a cardboard puppet or a lightweight walking robot. Good for expressive faces, flapping wings, moving arms and any build where the mass of a standard servo would be a pr...
Hummingbird Joystick
·
A thumb joystick with an integrated push button, wired for the Hummingbird controller. Two axes plus a click is enough to drive a rover, aim a servo turret, or — paired with a dial sensor — build a custom controller for Scratch or MakeCode Arcade games. Compatible with the Hummingbird Bit and the...
Hummingbird Light Sensor
·
An analogue light sensor on a Hummingbird lead: the brighter the light falling on it, the higher the signal voltage your program reads. Useful for nightlights that switch themselves on, sun-tracking models and any project where the robot should notice a shadow. It screws into a sensor port on the...
Hummingbird Position Servo (FS5103B)
·
Tell this servo an angle between 0 and 180 degrees and it travels there and holds. That makes it the right pick for arms, levers, opening jaws, gauge needles and anything that has to sit still at a known position. Connects to a servo port on the Hummingbird controller and is driven by a single bl...
Hummingbird Rotation Servo (FS5103R)
·
Where a position servo goes to an angle, this one keeps spinning — your code sets speed and direction instead. Add a Hummingbird Servo Wheel to each of a pair and last lesson's cardboard build becomes a mobile robot. Recommended for the Hummingbird Bit. On the older Hummingbird Duo, a gear motor ...
Hummingbird Servo Extension Cable
·
A 50cm extension lead for Hummingbird servos, for when the moving part ends up further from the controller than the standard cable allows — the head of a puppet, the top of a tower, the far end of an arm. Fits servo models HS-311, FS5103B, FS5103R and FS90, on both the Hummingbird Bit and the Hum...
Hummingbird Servo Plastic Block Adapter (LEGO Compatible)
·
Bridges the gap between Hummingbird servos and plastic building blocks. Mount the adapter on a position or rotation servo and LEGO-compatible bricks, beams and axles clip straight on, so students can build the mechanism properly instead of reaching for the hot glue. Fits servos used with the Humm...
Hummingbird Servo Wheel
·
A wheel that bolts onto the horn of a Hummingbird servo. Fit two to a pair of rotation servos and a student-built chassis can drive itself around the room. Sold individually, so most rovers need two. Suits servos on both the Hummingbird Bit and the Hummingbird Duo.
Hummingbird Single Colour LED - Green
·
A spare green LED for the Hummingbird system. The 5mm LED is pre-wired to a 50cm braided cable that screws straight into a Hummingbird controller's LED terminals — there is no breadboard, no resistor and no soldering to sort out first. Forward voltage 1.6V to 2.0V, rated for 20mA. Suits both the ...
