With a low power consumption of just 5mA and a robust design suitable for various applications, this module is perfect for both educational and industrial uses. ## Description AJ-SR04M-T-X ultrasonic ranging module is designed by using a waterproof stripline probe integrated with transceiver and receiver and non-contact ultrasonic detection technology. In the range of 20 cm to 600 cm, the product can accurately detect the distance between plane objects, and in the range of 20 cm to 250 cm, it can accurately measure people.Specification：Electrical parameters: JSN-SR04TResolution: about 0.5cmAngle: less than 75 degreesAcoustic emission frequency: 40khz Wiring: + 5V (positive power supply)Trig (control side) RXEcho (the receiver) TXGND (negative)The basic working principle:(1) Using IO port TRIG trigger location, to at least 10us high-level signal;(2) Module automatically sends 8 40KHz square wave, automatically detect whether there is signal return;(3) A signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;The use of this module is simple, a control mouth made a 10US above the high level, you can wait for the reception of high-level output. An output can be opened timer time, when the mouth becomes low when you can read the value of the timer, this time for the distance of time, can calculate the distance. Such a continuous cycle measurement, which can be measured to achieve the value of your move.Package Included:2* JSN-SR04T Ultrasonic Distance Measuring Sensor Review: Well Water Tank Level Gauge! - Got this quickly dialed in with an ESP microcontroller and ESPHome via Home Assistant. The sensor itself appears to actually be made for installation in a car bumper or similar the way it's molded, but hey it mounted great in to a 3/4" PVC coupling and is pointed down at the water surface in my well tank. It's been running non-stop for several months now, and while there's some occasional variation in the readings, and I do apply smoothing filters to the readings and calculations, it's otherwise doing exactly what I intended it to do at this price point! Your mileage may vary, as this is a component made for any number of ultrasonic sensing applications well beyond my usage. However, during commissioning of my project and testing on static surfaces, the measurements (in meters raw) provided from the module data pin were spot on with my actual field measurements. Review: Good modules and correct readings - Even though the picture says, AJ-SR04M, i got 2 modules of RCWL-1655. I was able to get exact reading and intend to use for measuring water levels in tanks. For pi, i used a voltage divider of 1kohm and 2kohm and was able to get correct readings Very happy with this module have to see the reliability on long term ## Features - Working voltage:DC3-5.5V, Static current:5mA, Total current work: 30mA. Working range: 25cm-4M, Working frequency: 40KHZ, Detecting angle: 75 degree. The JSN-SR04T ultrasonic distance measuring module provides a measurement range of 21cm-600cm. Blind area is 20cm. - Integrated with sealed waterproof stripline probe, this sensor suitable for wet and harsh measurement occasions. Please note that the device is waterproof, but it couldn't work underwater. - Small size, easy to use, strong anti-jamming, high accuracy, low voltage and low power consumption. The module has a variety of modes that can be modified manually, suitable for testing and teaching experiments in different occasions. - Applications:It is widely used in horizontal distance ranging, obstacle avoidance, object distance measurement, car reversing sensors, security alarms, automatic control, security and industrial control, Intelligent traffic control and artificial intelligence teaching and research etc. - Package Included:2 x JSN-SR04T Ultrasonic Distance Measuring Transducer Sensor Waterproof ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08T5XF6Y9 | | Brand | Atnsinc | | Brand Name | Atnsinc | | Customer Reviews | 4.0 out of 5 stars 29 Reviews | | Item Weight | 0.08 Kilograms | | Item weight | 0.08 Kilograms | | Manufacturer | Atnsinc | | Min.

I cut off enough of the narrow end of the plastic horn, until the sensor fit snugly. The abrupt end of a narrow tube may create an echo of its own (due to impedance mismatch), and furthemore sound may bend around sharp edges. Horns are made to mitigate these effects. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well Water Tank Level Gauge! *by S***. on 17 February 2026* Got this quickly dialed in with an ESP microcontroller and ESPHome via Home Assistant.

The data coming out is gibberish and unusable. My guess, the electronics are not designed to handle minor ESD events. The transducers themselves are fine. ## Frequently Bought Together - 2Pcs JSN-SR04T Integrated Ultrasonic Distance Measuring Sensor Transducer Module Waterproof - ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA Compatible with Arduino IDE (3PCS) - 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 --- ## 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.es/products/545936238-2pcs-jsn-sr04t-integrated-ultrasonic-distance-measuring-sensor-transducer-module](https://www.desertcart.es/products/545936238-2pcs-jsn-sr04t-integrated-ultrasonic-distance-measuring-sensor-transducer-module) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-22*
