Protobot.xyz borns with some basic types of native Sensors.
1 Mood Sensor
2 Moody Sticker
3 Moody Led
4 Timers
Any of them use a different CODE, here's some examples:
1-BTC_XMR (Mood Sensor)
Type 1 Mood Sensor. Targets a pair and shows the buy/sell mood using several led lights.
2-BTC_ETH (Moody Sticker)
Type 2 Moody Sticker. Targets a pair and shows the buy/sell mood using a single led light and the pair label.
3-BTC_ETH (Moody Led)
Type 3 Moody Led. Targets a pair and shows the buy/sell mood using a single led light. It is natively built in order to be embedded somewhere, since there are no indications about the light behaviour/nature.
4-BTC_ETH (Timer)
Type 4 Timer. Targets a pair and plays a sound once a market condition is reached.
Some are still under construction!
