It converts air pressure into relative altitude and sends it to your EdgeTX radio in real time, accurate to ±0.5m – ideal for planes and gliders. At 3.5g it disappears into any model, and a pass-through port lets you chain more ERS sensors.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-01.jpg\" alt=\"RadioMaster ERS-BA01 barometric altitude sensor\"\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul class=\"afk\"\u003e\n\u003cli\u003eReal-time relative altitude telemetry, ±0.5m accuracy\u003c\/li\u003e\n\u003cli\u003eConnects to supported ExpressLRS PWM receivers via CRSF\u003c\/li\u003e\n\u003cli\u003ePass-through port to daisy-chain more ERS sensors\u003c\/li\u003e\n\u003cli\u003eTiny: 23.5 x 13 x 7mm, 3.5g\u003c\/li\u003e\n\u003cli\u003eConfigure and log with the RadioMaster Sensor Configurator LUA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-02.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-03.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-04.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-05.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-06.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-07.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-08.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-09.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-10.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/af-8591530950690-11.jpg\" alt=\"ERS-BA01 sensor\"\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating voltage\u003c\/th\u003e\n\u003ctd\u003e5–8.4V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating current\u003c\/th\u003e\n\u003ctd\u003e9mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAltitude accuracy\u003c\/th\u003e\n\u003ctd\u003e±0.5m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature range\u003c\/th\u003e\n\u003ctd\u003e-10°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e23.5 x 13 x 7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e3.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x ERS-BA01 barometric altitude sensor\u003c\/li\u003e\n\u003cli\u003e3x heat-shrink tube\u003c\/li\u003e\n\u003cli\u003e1x manual QR code card\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWorks with (available at AeroFlow)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/radiomaster-er6-2-4ghz-elrs-pwm-receiver\"\u003eRadioMaster ER6 PWM receiver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/radiomaster-er8-2-4ghz-elrs-pwm-receiver\"\u003eRadioMaster ER8 PWM receiver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/radiomaster-er8g-er8gv-2-4ghz-elrs-pwm-receiver\"\u003eRadioMaster ER8G \/ ER8GV receiver\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"afn\"\u003e\n\u003cstrong\u003eGood to know\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eReceivers without a dedicated UART need two PWM pins set as serial TX\/RX in the receiver's Web UI or ELRS LUA.\u003c\/li\u003e\n\u003cli\u003eInstall the RadioMaster Sensor Configurator LUA on your EdgeTX radio to set up and view the sensor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"RadioMaster","offers":[{"title":"Default","offer_id":46415331196962,"sku":"AF-RM-ERSBA01-BAROMETRIC","price":1999.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/8562\/1794\/files\/1_1400x_b3ae9455-98ad-4af9-b968-8888f4001772.jpg?v=1787527292","url":"https:\/\/aeroflow.in\/products\/radiomaster-ers-ba01-barometric-altitude-sensor","provider":"AeroFlow","version":"1.0","type":"link"}
