Featuring a wide operating voltage (3.3-5.5V), a compact 2.54mm pitch design, and compatibility with Gravity I/O shields, these sensors deliver reliable real-time soil data to optimize your garden watering with precision and durability. ## Description Because many people say NE555 does not work, now we have changed to TL555,This analog capacitive soil moisture sensor measures soil moisture levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor It is made of a corrosion resistant material giving it a long service life Insert it into soil and impress your friends with the real-time soil moisture data This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V This sensor is compatible 3-pin "Gravity" interface, which can be directly connected to the Gravity I/O expansion shield Review: Accurate and Not the cheap one Review: MALO - TIENE NE555 Y NO TL555, SUPONGO QUE ES SURTE ## Features - Chip is TL555 - Operating Voltage: 3.3 ~ 5.5 VDC - Output Voltage: 0 ~ 3.0 VDC - PH:2.54MM ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SYBSHGX | | Brand | SongHe | | Brand Name | SongHe | | Country of Origin | China | | Customer Reviews | 4.2 out of 5 stars 210 Reviews | | Item Dimensions | 9.8 x 2.3 x 1 Centimeters | | Item Weight | 90 Grams | | Item dimensions L x W x H | 9.8 x 2.3 x 1 Centimeters | | Manufacturer | Songhe | | Material | Ceramic , Metal | | Material Type | Ceramic, Metal | | Maximum Supply Voltage | 5.5 Volts (DC) | | Measurement Accuracy | ±15% | | Model Number | F24 | | Mounting Type | Tabletop | | Output Type | Analog | | Sensing Distance | 98 Millimetres | | Specific Uses For Product | Intelligent agriculture, Moisture detection, Garden plants | | Style | Modern | | Style Name | Modern | | UPC | 738678030462 | | Upper Temperature Rating | 55 Degrees Celsius | ## Product Details - **Brand:** Songhe - **Item Weight:** 90 Grams - **Item dimensions L x W x H:** 3.86 x 0.91 x 0.39 inches - **Material:** Ceramic Metal - **Style:** Modern ## Images ![Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 5PCS) - Image 1](https://m.media-amazon.com/images/I/71I+61-rohL.jpg) ![Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 5PCS) - Image 2](https://m.media-amazon.com/images/I/61gPNMShOdL.jpg) ![Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 5PCS) - Image 3](https://m.media-amazon.com/images/I/611Zz8ixhmL.jpg) ![Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 5PCS) - Image 4](https://m.media-amazon.com/images/I/61KyqHJiZgL.jpg) ![Capacitive Soil Moisture Sensor Corrosion Resistant for Arduino Moisture Detection Garden Watering DIY (Pack of 5PCS) - Image 5](https://m.media-amazon.com/images/I/61wQRDRX3tL.jpg) ## Questions & Answers **Q: do you have a library for the arduino? How do I calibrate these? Getting an analog reading does not mean anything..** A: Take a reading while they are dry (that's your 0% reading), then take a sample of your soil and put it in a pot, insert the sensor and then water the pot until it can't hold any more water, then take another reading that's 100% saturated. If you want you can put the sensor near a plant and see what level it reads when the plant looks stressed from to little water and make sure you keep it wetter than that. Note: unless you are measuring pots, the moisture level near the surface is about useless for most plants unless they have very shallow roots.. for plants with deeper roots you probably want to waterproof the top portion of the sensor and bury it about 18" down. **Q: What is the max distance from a pi using 3v3 and using cat5 cable can the sensor be and still work ok?** A: so not sure if you still need this answered or not, but for others it might help. Im using an Arduino 5v, I used about 10 feet of cat5 cable from arduino to sensor. it changed the value some but you just need to calibrate it for that change. example, Arduino to senor without cat 5 = wet "850" / dry "450" arduino to sensor with 10 feet cat 5 = wet "700" /dry "300" **Q: how does this work? do i have to connected to something else?** A: Yes. Depends on what you want to do with it. The output is a voltage value. You can connect to an Adruino type device to display it as analog or convert it to a calibrated digital display of percent moisture. **Q: Will this work (as is) with the Micro:bit?** A: I dont know understand your question. I plugged it into a data port on a esp 8266 read the data using C+ and calibtrated it to meet my needs and transmitted it to a Blynk Control Panel on the internet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate and Not the cheap one *by S***Z on 24 December 2024* ### ⭐ MALO *by P***Y on 5 June 2025* TIENE NE555 Y NO TL555, SUPONGO QUE ES SURTE ### ⭐⭐⭐⭐⭐ High quality *by J***O on 5 February 2026* ## Frequently Bought Together - Songhe Capacitive Soil Moisture Sensor Module Corrosion Resistant Moisture Detection Garden Watering for Arduino DIY 3.3~5.5V 5pcs - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - HiLetgo 2pcs DHT22/AM2302 Digital Temperature And Humidity Sensor Module Temperature Humidity Monitor Sensor Replace SHT11 SHT15 for Arduino Electronic Practice DIY --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/385380442-capacitive-soil-moisture-sensor-corrosion-resistant-for-arduino-moisture-detection](https://www.desertcart.is/products/385380442-capacitive-soil-moisture-sensor-corrosion-resistant-for-arduino-moisture-detection) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-22*
