Hi all I'm searching for the sensor to measure the weight of the water inside the water bottle and one request is that sensor size to be a small be as to fix at the bottom of the water bottle.

Water bottle Spec: 0.5 litre or 1 litre water bottle

For example: if i fill water into bottle as a 0.5 litre I have to show that 500gram of water ..and for ur notice that reading is not an issue I can connect that via any application but the main thing I need here is I have to measure it. and if further info need means kindly let me know guys.

kindly help me with this guys.

Thanks in advance.

    If you don't want to modify the bottle, you could put a small load cell under it to measure its weight. /challenges-projects/design-challenges/sixth-sense-design-challenge/b/blog/posts/sixth-sense-mechanical…

    For such applications, you should probably use a strain gauge based compression load cell. Such sensors aren't very big, some have integrated amplifiers and even digital outputs. This is similar to technology used in weighing scales which usually use larger beam-type strain gauges.
