The REES52 Promise
The REES52 Promise
We want you to build, not worry. Here is exactly what happens if something goes wrong with your order.
Dead on arrival or defective? We replace it.
If your item is dead on arrival or has a manufacturing defect, tell us within 7 days of delivery. Email support@rees52.com with your order number and a short video or a couple of photos showing the problem. Our team will get back to you within 24 hours and arrange a free pickup from your doorstep - you never pay return shipping for a defective item. Once we verify the issue, your replacement ships out right away. If the item is out of stock, you get a full refund instead.
Refunds, with real timelines.
- Approved refunds go back to your original payment method within 6-7 working days.
- Missing item in your package? Tell us within 7 days with photos of what arrived and the parcel label. Once confirmed, the refund for the missing item reaches you in 2-3 working days - or we ship the missing piece free, your choice.
- Every refund comes with a reference number by email or WhatsApp, so you can track it with your bank instead of chasing us.
Wrong item or not as described?
Email us your order number and a photo of what you received. We arrange the return pickup, and ship the correct item as soon as the return is on its way. Prefer your money back instead? That is fine too - full refund, same 6-7 working day timeline.
About lead times on some products.
A few items on rees52.com are sourced from our overseas partner warehouses and are not sitting on our shelf. Those products show a lead time of about 20-25 working days on the product page, before you pay. If you order one, we keep you posted as it moves. Changed your mind while waiting?

Description:
Worried about silent LPG or propane leaks in your home, kitchen or workshop? With the MQ-6 Gas Sensor Module you gain a fast-responding, reliable detector that senses combustible gases like LPG, butane, propane and natural-gas before they become a hazard.
The MQ-6 sensor module is designed for practical use in both DIY electronics and safety systems. Built around a metal-oxide semiconductor (SnO₂) sensing element, it measures changes in conductivity when combustible gases are present. It's highly sensitive to LPG (propane, butane) and suitable for integration with microcontrollers such as Arduino or Raspberry Pi.
With dual outputs — analog (0-5 V) and digital (TTL) — you can choose to either read a continuous concentration range or trigger an alarm when a preset threshold is exceeded.
The module integrates easily: power it with 5 V DC, allow a short pre-heat time, wire the analog output to your ADC or digital output to your microcontroller, and it’s ready to monitor your environment. For example, it can be installed in kitchens, workshops, gas cylinder areas, automotive fuel-system checks, industrial safety panels, and more.
Specifications:
| Model | MQ-6 |
| Detectable Gases | LPG (mainly propane & butane), Natural Gas/CH₄ (limited) |
| Detecting/Concentration Range | ~200-10,000 ppm (some sources 300-10,000ppm) |
| Operating Voltage | 5 V DC ±0.1 V |
| Heater Voltage | 5 V ±0.1 V AC or DC |
| Heater Resistance | ~30 Ω ±3Ω |
| Current Consumption | Approx. 150-mA typical (varies) |
| Analog Output | 0-5 V, proportional to gas concentration |
| Digital Output | TTL logic 0/5 V when threshold exceeded |
| Operating Temperature | –10 °C to +50 °C (some sources –20 °C to +40 °C) |
| Operating Humidity | <95% RH (non-condensing) |
| Module Dimensions | ~32 mm × 20 mm × 22 mm |
| Material / Sensing Element | SnO₂ (Tin Dioxide) sensitive material on ceramic tube |
Features:
- High Sensitivity to LPG/Propane/Butane: Detects low levels of combustible gases so you can warn early.
- Analog + Digital Output: Choose continuous monitoring or simple threshold-trigger alarm integration.
- Works with 5 V Supply: Compatible with standard microcontroller systems (Arduino, Raspberry Pi, ESP32).
- Simple & Low-cost Implementation: Easy to wire and incorporate into safety or IoT systems without complex signal chains.
- Wide Application Range: From home/kitchen LPG leak detection to industrial combustible-gas alarms and custom electronics projects.
- Compact Form Factor: Small size (approx. 32mm × 20mm × 22mm) makes it easy to mount in tight spaces.
Package Included:
- 1 x MQ-6 Gas Sensor Module - Detects Propane, Butane, LPG and Natural Gas
