The ACS712-20A current sensor module is a widely used current sensing device based on the Allegro ACS712 Hall Effect-based linear current sensor IC. This module is designed to measure both AC and DC currents up to ±20 Amps and provides an analog voltage output proportional to the current.
Key Features:- Hall Effect-Based Measurement: Provides isolation between the sensed current and the output signal.
- Current Range: Measures currents up to ±20A.
- High Sensitivity: 100 mV/A (for the ACS712-20A version).
- Output Voltage: Analog output voltage centered around 2.5V (for zero current).
- Bidirectional Current Sensing: Measures both positive and negative currents.
- Electrical Isolation: Isolation between the input current path and the output signal.
- Compact Size: Suitable for embedding in PCBs or standalone applications.

Tp4056 With Current Protection
Product Price: Rs 14 / PieceGet Best Price
Product Brochure
Product Details:
| Part Number | Tp4056 |
| Pawer | 12V |
| Current Rating | 3A |
| Battery Type | Lithium Ion Battery Charger |
| Dimensions | 3X2X1 cm |
| Indicator Light | Yes |
This TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection is a tiny module, perfect for charging single cell 3.7V 1 Ah or higher lithium-ion (Li-Ion) cells such as 16550s that don’t have their own protection circuit. Based on the TP4056 charger IC and DW01 battery protection IC this module will offer 1A charge current then cut off when finished.
Furthermore, when the battery voltage drops below 2.4V the protection IC will switch the load off to protect the cell from running at too low of a voltage – and also protects against over-voltage and reverse polarity connection (it will usually destroy itself instead of the battery) however please check you have it connected correctly the first time.
Manufactured under fully machinery processing. Each module is tested OK before shipment so it has high reliability for the best performance. In conclusion, it is special design for a single lithium battery charging. TP4056 Other features include the current monitor, under voltage lockout, automatic recharge, and two status pin to indicate charge termination and the presence of an input voltage.
Using the module:- Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
- Connect cell to charge to B+/B- pads on the right-hand side of the module.
- A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
- Important! Disconnect load when charging
- The red LED indicates charging in progress, green LED indicates charging has finished.
- Never charge your battery at a rate greater than 1C.
