It measures up to 2 bar (about 10 meters water depth) with a depth resolution of just 0.16 mm and can also measure in-air altitude with 13 cm resolution. This makes it ideal for shallow-water devices where a high level of resolution is required. It includes a temperature sensor accurate to ±2 °C and is supported in ArduSub 4.7 and later.\u003c\/p\u003e\n\u003cp\u003eThe Bar30 is a high-pressure sensor using the Measurement Specialties MS5837-30BA. It measures up to 30 bar (about 300 meters water depth) with a depth resolution of 2 mm, making it a great choice for deep-water ROVs and general underwater instrumentation. The built-in temperature sensor has ±4 °C accuracy, and is supported by ArduSub and other ArduPilot firmware.\u003c\/p\u003e\n\u003cp\u003eBoth communicate via I²C and operate on 3.3 V logic (with 5.5 V max power input). The PCB includes four solder pads for ground, 2.5–5.5 V power, and 3.3 V I\u003csup\u003e2\u003c\/sup\u003eC connections.\u003c\/p\u003e","brand":"Blue Robotics","offers":[{"title":"Bar02","offer_id":58747058291062,"sku":"BR-100999","price":42.0,"currency_code":"EUR","in_stock":true},{"title":"Bar30","offer_id":58747058323830,"sku":"BR-100747","price":50.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1017\/5745\/2662\/files\/BAR-PCB-VP-1.jpg?v=1789583004","url":"https:\/\/www.substore.fi\/products\/pcb-for-bar-depth-pressure-sensors","provider":"Sub Marine Store","version":"1.0","type":"link"}
