‘Tepmachcha’ is an Open-Source Flood Early Warning System using Sonar and FONA
Built around a Seeeduino-Stalker v3, FONA 808, Maxbotix sonar, XBee, and OSH Park-available custom PCB, the project Tepmachcha is named after a mythological fish avatar and has been appropriately adopted to an open-source initiative for constructing a ‘flood early warning’ system for places like Cambodia where residents are vulnerable to water surges. It’s a great-looking project; and thanks to Rob and the DAI team for doing all this good work – the world is a better place because of it.
Tepmachcha is an open source sonar stream gauge designed to give early warning of flood conditions to residents in vulnerable areas. When a flood condition is detected, Tepmachcha triggers a call with a voice recording via the RapidPro interactive voice response (IVR) system. It also records water levels at regular intervals for later analysis of flooding patterns or to inform more complex hydrological analysis.
Tepmachcha was designed at the DAI Maker Lab in collaboration with People in Need Cambodia with funding from USAID’s Development Innovations project, People in Need, and DAI. It is a fork of the Hidrosónico sonar stream gauge piloted by DAI in Honduras as part of the USAID Proparque project. It is released under the MIT License.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
