# Hall effect sensor (analog,threshold)

**Type:** Product page · **SKU:** CE09441 · **Brand:** [Core Electronics](https://core-electronics.com.au/brands/core-electronics-australia)
**Page:** https://core-electronics.com.au/hall-effect-sensor-analog-threshold.html ([markdown](https://core-electronics.com.au/hall-effect-sensor-analog-threshold.html.md))

Sense invisible magnetic fields around you! Use the adjustable digital output to set a threshold or the analog output to get a gauge of the distance.

## Pricing

- **Price:** $1.80 (inc GST) — $1.64 AUD, exc GST
- **Quantity discounts:** 25+ $1.55 (exc GST) · 50+ $1.47 (exc GST) · 100+ $1.39 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 34 today; more stock is typically available with a 8–12 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09441:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE09441:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Sense invisible magnetic fields around you! Use the adjustable digital output to set a threshold or the analog output to get a gauge of how far away a magnet is or sense ambient fields around you!

Pair with [a small cube magnet](https://core-electronics.com.au/magnet-square-0-125.html) to make a puzzle box or a simple short-distance range sensor.

### Specifications

- Voltage input: 2.7-6.5V
- Onboard LED for power and going over the adjustable threshold

### Examples

#### Raspberry Pi Pico - Micropython

 ```
from machine import ADC, Pin
import time

a0 = ADC(Pin(27))  # Create an ADC object on pin 26 (ADC0)
d0 = Pin(22, Pin.IN, Pin.PULL_UP)  # Digital output from sensor

while True:
    reading = a0.read_u16()  # Read the value from the analog interface
    print("Sensor reading:", reading)
    
    threshold_exceeded = d0.value()  # Read the value from the digital interface
    if threshold_exceeded:
        print("Threshold exceeded!")
    
    time.sleep_ms(500)  # Wait for half a second before reading again
```
